I heard the max level for dweller is 50, but idk why I have a dweller level 61. Got him originally from the lunchbox, and let him out loot for items until he level up to 50, then got him back in the vault and put some training on him, and he kept leveling up to 61 now...but I cant get caps everytime he levels up. Kinda weird, idk how to upload picture in this forum, but I'm pretty sure that's level 61 and I'm not drunk...he is the only one I have that level over 50...

I've heard some pets let them level higher, did you give him a pet?
