Since players can only close one vent, and the fact there are DAVE and Salvage Cube in together again, it means that if they split up and show up in different vents, it means game over.

Decided to make it so that both Salvage Cube and DAVE can only enter the vent whenever neither of them are in a vent (To explain it a bit better, for example if DAVE is in cam13, Cube won't be able to enter any vent until DAVE leaves the vent (either by progressing or being blocked off))

Withered N. Spidor now also gets stalled in the vents if Fizzlepop is in the office (only for the 3rd CN variant, everywhere else is the same)
