When the golden backpack is filled with items, then put on and taken off again, some items inside go missing. It's a bit hard to describe; I can send a video if needed.

I'd be glad if it's possible

Fix will be released today, thank you for video

I send google drive link to u, file is too large I can't send it directly.
