when i open 079 chamber door 2 everything is black and no 079 in chamber
Version 1.3.11
Modded:Yes

this is a bug in the base game, its rare but what happens is sometimes for a reason i dont know of, 079 room will not work on certain map seeds or custom maps. you will need to start a different map seed or if it a custom map, change position of 079 room slightly and it should work.
