The neon hum of the Neural Gateway suddenly pitched into a dissonant scream. Across the command deck, "Verified" status lights blinked in a rhythmic, mocking green—the system believed everything was perfect, but the reality on the floor was a geometric nightmare. INCIDENT REPORT

Check for spawn space → Fail.
Apply compression force to existing units → No effect.
Double the compression force → Entities overlap, breaking collision logic.
Trigger emergency garbage collection → Entity manager crashes.


Spawn validation needs a buffer check – not just “can any enemy fit?” but “can all enemies in the wave fit without overlapping or breaching the gateway?”
Gateway should pause or despawn enemies first before self-destructing, or at least trigger a fail state that makes sense (e.g., wave skip, partial spawn, or warning on gateway UI).
This seems most common with tight chokepoint defenses, stacked spawn blockers, or modded maps with altered collision.

Clear a Large Flat Area: Ensure there is a significant, unobstructed platform (often at least 10x10 or larger depending on the gateway type) with plenty of vertical clearance. Check for spawn space →  Fail
This specific error message originates from the implementation details of the research paper: Spawn validation needs a buffer check – not
