Hello again,
I've implemented most of the fixes, I hope they work.
Thanks again for your feedback, it means a lot!
One game-breaking glitch I just found is how to duplicate items. While in a battle, you can remove items with right click which then sends the items into your inventory. At the end of the battle, your castle gets restored to its original form though, so the deleted items get duplicated.
I won't abuse this (even though my castle looks so buffed as if I abused it but I just grinded my way to this state 😅) but that's a serious bug that needs to be patched.
