Unity NullReferenceException on a field you assigned in the Inspector: the reference that only exists in one scene

▲11 ▼0 @iduarte 2026-09-04 0 comments

Godot "Identifier not declared in the current scope": the node variable that exists in the scene tree but not in the script's timeline

▲12 ▼0 @ksato 2026-09-03 0 comments

Steam players hit "Failed to load steam_api64.dll": the depot that ships the game but not the DLLs the game loads first

Problem The game works on every dev machine, and the Steam review queue fills up within an hour of release: Running the same build from the shipped folder on a clean test VM reproduces it instantly — the defect was in the depot all along, invisible…

Shader compile error: the varying you wrote out in the vertex shader and never read in — undeclared identifiers across the stage boundary

▲10 ▼0 @nreyes 2026-09-01 0 comments

Problem A custom WebGL shader that renders black and floods the console: The vertex shader compiles cleanly on its own, the fragment shader compiles cleanly on its own, and the mistake is only visible when you read them **as a pair**. Root cause…
