Quick answer: Watch for players reporting they're stuck and can't advance, complaints clustering at a specific point, players halting at the same place, and an objective that won't complete. A progression blocker stops players cold.
A progression blocker, a bug that prevents the player from advancing, ends their experience just as surely as a crash, often without any error. Here are the signs your game has a progression blocker.
Players Reporting They're Stuck and Can't Advance
The direct sign is players reporting they're stuck, can't advance, can't complete an objective, or are blocked from progressing. A progression blocker halts the player at a point with no way forward, so it generates direct complaints about being unable to continue, often without a crash, just stuck.
Bugnet captures crashes and context, so issues at the blocking point are identifiable. Players reporting they're stuck and can't advance is the direct sign of a progression blocker, and since it often has no crash (the game runs fine, the player just can't progress), capturing the context around where players get stuck (breadcrumbs, the state) helps you find the blocking condition to fix.
Complaints Clustering at a Specific Point
A telling sign is complaints clustering at a specific point in the game, many players reporting being stuck at the same place. A progression blocker is usually at a specific point on the path, so complaints concentrating there pinpoint the blocker, the specific objective, area, or step where players halt.
Bugnet captures crashes with breadcrumbs, so you can see where players halt. Complaints clustering at a specific point are a sign of a progression blocker there, and the concentration pinpoints it, the specific place players get stuck, so you can investigate and fix that exact point (an objective that won't complete, a trigger that doesn't fire, a state players can't get out of).
Players Halting at the Same Place in Your Data
A data sign is players halting at the same place, a drop-off or stuck-point cluster where players reach a spot and stop progressing. If your data shows players consistently stopping at one point (not because the content ends, but because they're blocked), a progression blocker is likely halting them there.
Bugnet captures crashes with breadcrumbs, so you can correlate halts with where players are. Players halting at the same place in your data is a sign of a progression blocker, and seeing where they halt (via breadcrumbs and drop-off points) locates the blocker, the specific point players can't get past, so you can examine and fix what's blocking them there.
