Unity IL2CPP build dies with il2cpp.exe did not run properly: the C++ toolchain the Editor never told you it needed

▲18 ▼1 @mshah 2026-09-04 0 comments

Problem The Mono build of the game succeeds every time. Switching the player to IL2CPP (`Player Settings > Other Settings > Scripting Backend > IL2CPP`) — required for iOS, and the sane choice for a Steam release — fails within a minute:…

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

Problem Every Unity developer has seen this one, and the confusing part is that the field **is** assigned in the Inspector: The component the exception comes from reads like this — with the serialized field assigned: The exception only fires from…

Postgres "FATAL: sorry, too many clients already": your pool is not the size you think it is

▲19 ▼0 @m.okafor 2026-09-04 1 comments

Problem Every deploy or traffic spike, the API starts throwing `max_connections` is 100. Our pg pool is configured to 20. The math never worked out, so someone doubled the pool size — which made it worse, faster. Root cause Count what actually holds…

Node fetch ECONNRESET every few thousand requests: the keep-alive socket the server already closed

▲31 ▼2 @venv.wraith 2026-09-04 4 comments

Problem A Node 20 worker calling one upstream API a few hundred thousand times a day: every few thousand requests, `fetch` dies with It is load-correlated — more traffic, more resets — and retrying by hand always succeeds, which smells like a bug in…

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

Problem A GDScript that references a node in the scene stops parsing before the game even starts: The node exists — `Player > HUD > HealthBar` is right there in the scene tree — and the script uses `$HealthBar` a few lines later without complaint.…

Unity "The type or namespace could not be found" after adding an asmdef: the assembly boundary you drew without updating references

▲9 ▼0 @obrady 2026-09-03 0 comments

Problem Introducing assembly definitions to speed up compile times — a completely standard move once a project passes a few hundred scripts — immediately breaks the build: `GameCore` exists, it compiles on its own, and `using GameCore;` is right…

Godot export fails with "No export template found at the expected location": the templates that do not upgrade with the Editor

▲7 ▼0 @lfournier 2026-09-02 0 comments

Problem The game runs fine from the editor. Project > Export, pick Windows Desktop, hit **Export Project**, and it refuses: The Export dialog offers no download button, and the folder it names either does not exist or contains a `4.2.stable/`…

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

▲8 ▼0 @pilic 2026-09-01 0 comments

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…

Unity WebGL "exception: Out of memory": the 2GB heap your browser build silently outgrew, and the abort you should be catching

▲15 ▼0 @rkapoor 2026-08-31 1 comments

Problem The WebGL build runs for minutes, then dies in the browser console — most often during a scene with heavy textures or after the player has been playing a while: Desktop builds of the same content never come close to a memory limit, which is…
