I have found a bugg in latest baggins.
When you have two Bags open like when you are at the bank. If one bag has one free slot and you transfer an item so one bag gets full, the empty square with free slot count disappear from both bags.
If a bag without empty slots get new empty slots by trasfering of items the empty slot with counter does not appear until bag is closed and open again.
Suggestion is to always keep the empty slot but have the counter to 0 when the bag is full if no better solution can be found. I often use the empty slot when i wanna transfer partial stacks from the bank. like 15 herbs instead of a whole 20 stack.
Thnx for a great mod!
