Okay thanks! I think I may know whats causing the crashing so I will definitely have that fixed by next patch.
I have no clue what could be causing the knight to have lost its items, but I will do some deep playtesting and see if I can recreate that bug as it sounds quite extreme.
I may consider allowing rerolling units (especially as adding more units will only make it more difficult to get specific units), though there is also another feature I want to add in the future that should allow much more choice over which units you can obtain for a higher price. Hopefully as more units/enemies/items are added and I continue to playtest the difficulty should become more balanced, and those pesky slimes shouldn't be as big of a threat :)
What do you think makes the guard and knight so much weaker compared to the wizard?
