i dont know whats going on.. now every time i rush at 17-29% i fail.. rad roaches comes out and kills my dwellers.. high lvl ones too. before they did come out too and same dwellers killed them..now it takes more dwellers to kill them. my resources are full yet they suffer from radiation and electricity is always red.. even if it shows its up to max and even after building more power plant.. disaster happening every few minutes... and rush never fails at 39 % and sometimes i cant rush cause it shows 1450% what does that mean.. its not like im rushing all the time that it will rise that high.. i always keep dwellers bz so no ones wasting food or water yet resources keeps falling

The enemies that spawn from room failures are scaled based on the upgrade level of the room.


Don't upgrade rooms to lv2 until you have a couple people with guns in the room....


I don't upgrade anything to level 3 anymore. It's not worth the hassle of super tough disasters. Too many stim packs....


I don't mean three rooms combined...thats fine....just don't upgrade the rooms to level 3...

1450% of failure?

Either that's a typo or your vault has some serious problems!
