Thank you for coming back for this: I started up Div2 to check the inventory settings but now the bug seems to have gone (?!). I don't know if the maintenance on Tueday is the reason, I havent played since Sunday so this came as a surprise for me. I switched off/on the game twice and both times the inventory settings did not reset.
A happy accident as bob ross would have said haha, let me know if it starts happening again though and we'll check it out further okay?
Have a wonderful evening/morning/night/afternoon ๐
