A few things suggest there may be a bug in the difficulty of lightfinger challenge
Prior to update 12 I could consistently get through second boss in lightfinger now it is very rare and I sometimes even lose a couple of characters in room 1 (something that never happened before). I typically bow out now in room 3 or 4 but sometimes earlier.
my characters are level 12-13 yet the enemies in rooms 1 sometimes start at level 18 (albeit they are typically just animated armours). These random level 18 rooms don’t appear until room 4 or 5 in mind flayer.
the enemies in other challenges get higher as you progress, yet when you start with level 18 enemies in room 1 you also see level 18 in room 8
I’m 3 dicing mind flayers consistently yet I almost always 1 dice lightfinger now, rarely 2 dice and sometimes zero dice.
Early rooms (1-4) starting at too high difficulty level?
