Alright, so either this infestation spawned super god-mode radroaches, or they were bugged unkillable. It only spawned about 3 radroaches if i counted right, and it tore right through the 3 people I had in the room, all of which had weapons.....I revived them, and sent 3 other people from other rooms, all with weapons as well, and the radroaches proceeded to kill the 3 I revived, as well as the others I sent in for backup, and not a single radroach was killed.....I can't see how this could be working as intended, I'm sorta new so this pretty much wiped out almost half of my shelter and wasted a bunch of caps in the process. I've had plenty of radroach infestations in the past few days since I started playing, but none of them turned out this bad...even had bigger infestations too...

edit- as I put my phone down to write this post, I didn't want to send any other dwellers in for a suicide mission so i decided to just see what happened, the infestation grew, and wiped 75% of my shelter, i barely have any dwellers left, all of my resources are low, and it's just a bad situation....if this is just a bug then I'll shrug it off and start over, but If this is something that is to be expected it makes me not want to play this game anymore, just saying...

Had the same happening to me. Can't see how this could be WAI.

I gave up on Shelter after that.

I might be doing the same. I told myself I would shrug it off and keep going, stuff like this happens in games.....but I'm just having the hardest time recovering, I have so many rooms now and so few dwellers to work in them, all of my bars are staying in the red and all of my dwellers are so low on health i cant risk rushing anything cuz if an accident happens it will kill the whole room lol....I'll keep trying but I'm with you on this one, this sorta killed the game for me. Might start over in a new vault though.
