Quick answer: Lower the snow accumulation gradually toward zero based on a melt rate while temperature is above freezing, and let the snow blend and footprints recede with it.
The sun comes out and all the snow disappears at once, which looks jarring. Snow should melt over time, with cover thinning and exposed surfaces clearing first.
How to fix it
1. Melt by rate, not reset
While temperature is above freezing, decrease the global snow accumulation by a melt rate per second so cover thins gradually instead of being zeroed instantly.
2. Melt exposed areas first
Bias melting by sun exposure and slope so sunlit, sloped surfaces clear before shaded flats, matching how real snow recedes and leaving believable patches.
3. Recede footprints and puddles
As snow melts, fade footprint deformation and optionally raise wetness/puddle accumulation so melting snow leaves wet ground rather than dry, then dries out.
Catching the ones you can't reproduce
The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.
Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.
This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
The bug you can't reproduce isn't gone — it's just invisible until you capture it from the player's device.
