Quick answer: Capture the in-game date and time, the save state, and the systems involved on life sim and farming game bug reports, because the genre runs a long calendar where time, crops, relationships, and events interlock. The date and save state are what let you reproduce a bug that depends on a specific point in a long, accumulating playthrough.

Life sims and farming games are built on time. They run a calendar across in-game days, seasons, and years, with interlocking systems, crops that grow on schedules, NPCs with daily routines, relationships that develop, festivals and events on specific dates, all evolving over playthroughs that span dozens of hours and hundreds of in-game days. The bugs that emerge, a crop that does not grow, an NPC stuck in their routine, an event that does not fire, a save that breaks after years of play, are tied to specific dates and accumulated state, which is exactly what you must capture to reproduce them.

Time is the organizing system

The defining structure of a life sim or farming game is its calendar. Everything happens on a schedule: crops grow over days, NPCs follow daily routines, shops have hours, relationships progress over time, and events occur on specific dates. This time-driven design means that a huge share of the genre bugs are time-dependent, occurring only on a particular day, at a particular time, or after a particular accumulation of in-game time.

This makes the in-game date and time the single most important context for a life sim bug. A report that the festival did not happen or the crop did not grow is meaningless without knowing the date and time, because those determine what should have occurred. Capturing the in-game calendar position on every report is the foundation of tracking these bugs, since it tells you what the game state should have been at that moment.

Capture the date, time, and save state

Capture the full in-game temporal context, the day, season, year, and time of day, plus the save state, on every report. Together these locate the bug precisely in the playthrough: the date tells you what scheduled events and growth should be occurring, and the save state captures the accumulated world, the crops planted, the relationships built, the progress made, that the bug emerged from.

Life sim saves can be large and detailed, encoding a long playthrough, so capture enough to reproduce, ideally the save itself. With the captured save and the date, you can load the exact moment in the player calendar and see whether the crop grows, the NPC moves, the event fires, as it should. This is the only practical way to reproduce a bug that depends on a specific point dozens of hours into a playthrough you could never reach by hand.

Interlocking systems create emergent bugs

Like other systems-heavy genres, life sims have many systems that interact, and bugs emerge at their seams. A relationship event that depends on a crop being harvested, an NPC routine that conflicts with a festival, a time-skip that interacts badly with a growth schedule, these cross-system bugs are the hard ones, because each system is individually correct but their interaction produces a wrong result on a particular day.

Capture which systems were involved when a bug occurs so you can focus on the interaction. A bug that involves the relationship system and the calendar system, an NPC who should have appeared for a relationship event but did not because of a scheduling conflict, is diagnosed by seeing both systems state at that moment. The interlocking nature of life sim systems means the date alone is often not enough, you need to see how the systems were interacting at that point in time.

Long saves and time-skip bugs

Life sims are played across long playthroughs and rely on saves that span in-game years, which makes them prone to long-save and accumulation bugs: a save that grows until it breaks, state that drifts over many in-game days, a value that overflows after enough time, a save-format change that breaks an old long playthrough. These only appear far into a playthrough, where casual testing never reaches.

Capture the playthrough length and the save version so you can spot these long-game bugs. A bug that only appears after many in-game years points at accumulation or drift, and a save-load failure tagged with an old version after an update points at broken backward compatibility, which is especially painful in a genre where players invest dozens of hours into a single save. Time-skip mechanics, sleeping to the next day, advancing the calendar, also concentrate bugs, so capture the context around them when reports cluster on day transitions.

Setting it up with Bugnet

Add an in-game report option and attach the in-game date, season, year, and time of day, the save state, the systems involved, the playthrough length, and the save version as custom fields and a serialized blob. Bugnet stores them so a life sim bug arrives with the temporal and accumulated context needed to load the exact moment and reproduce a time-dependent or long-save bug.

Enable automatic crash capture for the crashes that long saves and complex day transitions produce, and group identical issues into occurrence counts. When reports cluster on a particular date, like a festival day, or a particular day transition, you have found a time-specific bug, and the captured save and date let you load that exact calendar moment to reproduce it, which for a genre organized entirely around time is precisely the context that makes its bugs tractable.

Test across the calendar and long playthroughs

Because life sim bugs are time-dependent, testing must cover the calendar, not just the first few days. Use developer tools to jump to specific dates, festivals, and seasons, and to fast-forward a playthrough, so you can test the scheduled events and the long-game state that normal testing, which tends to stay near the start, never reaches. Each festival, season transition, and milestone is a distinct situation to verify.

Combine this calendar-spanning testing with your captured reports for the accumulated and emergent states you did not anticipate. Your testing exercises the scheduled events and the intended progression across the calendar, and the captured saves and dates surface the bugs that only emerge from a real player long, particular playthrough, the specific combination of crops, relationships, and choices that breaks an interaction on a certain day. For a game players invest dozens of hours into across in-game years, ensuring the calendar and the long save hold up throughout is the core of keeping that long journey free of the bugs that would waste the player time.

Life sims run on a calendar. Capture the date and the save, and you can stand in the player's exact day.
