Thank you for the report!

I gave this a test, and it seems to be caused by how the lighting system marks convex hulls (things that cast shadows) as "hidden" from the light's point of view if they're behind a wall or an obstacle. The issue here is the door goes behind the floor structure when it's closing, marking it as "hidden", and the light will ignore it from that point onwards. Need to think a bit about a way to address this (forcing the door to become "unhidden" for all lights whenever it opens/closes wouldn't be ideal, because it'd significantly increase the amount of light calculations and be bad for performance).
