The game keeps each kind of light (PbrSpotLight, PbrSphereLight, ...) in a table of 8,192 and crashes at Skate.exe+0x4ea4094 when a level makes more. - Each kind's light factory is hooked: once the kind's table is nearly full it gives no entity, as the game's own factory does for a light it should not make. The light is not drawn and the game goes on. - Said in the log: the kind of light and how many were left out. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
