Hey guys, wondering if anyone else came across this bug. It literally wiped out my entire vault of 30. It was caused from a Rush job and the other two radroaches died but the last one wouldn't.

I came across one of those just now. I logged on to see if anyone was having this issue, and there you are! It started in an empty storage room in my vault, and then spread to a nearby room. Though, usually if that room is occupied the radroaches don't spread but this time it did to like 7 other rooms. Luckily I am very far in the game so once it hit the rooms with dwellers equipped with massive dmg weapons they all died.

I don't know if this works on radroaches, but I've seen people say that immortal fires can be extinguished by shutting down the game completely and reopening.

Ahh, you ran afoul of the Murder Roach.
