Since the addition of new and stronger monsters (and even before the update) I have become increasingly frustrated to the point I will no longer be playing except to periodically check if it's fixed, when a room has a failure, the dweller begin scrambling all over the room making it near impossible to heal your dwellers. I have wasted 35+ stimpacks trying to beat one room but in the time it takes me to be able to click a dweller (after chasing them with my finger and accidentally clicking already healed dwellers a few times,) my others have already died. TOTAL CRAP. Since this update I have gone from 10k caps to 20 just from having to revive dwellers putting my vault exansion at a standstill. This has RUINED MY GAMEPLAY.
