RealGlorp reported that a named light_environment driven by engine.LightStyle updates world lightmaps but static props lose the sun after the first change and never get it back. Closed on 6 October; commit efb205 fixes engine.LightStyle only updating static props once.

The17thDoctor reported that a surface.DrawPoly() call with fewer than 3 vertices in PostDrawOpaqueRenderables breaks later calls in the same hook.
