I can't wait to play this game again once you're able to update it! I hope these bugs are an easy fix
I think the immunity would be a great way to balance it!
I think having duplicates can be good but every time I destroyed a building I got the same item (every time I started a new run it was with a different item but I still had enough duplicates for my whole team to have the same item and more X) ) I don't know how randomization works but maybe putting a limit of 4 duplicates (so every character on the team can still equip the same item) could help avoid this
Thank you for answering!
