Last night I just reached level 86 and power level 103. Upon logging in today, I had 12,000 emeralds, and only 2 artifacts on my character both level 100 with no armor and a level 1 bow, and level 1 sword. Also, I got to power level 67, but now I cannot do adventure or apocalypse Mode even though it says I've already completed everything on the normal difficulty.  I've already put several hours on this game and I wouldn't mind leveling my character back up, but I can't unless I'm playing with my friends due to me not having access to the other difficulties to get better loot.
