#35 File corruption on classic character

[Atrocious Nightmare]

When I first created this pre-expansion character I had no problems handling items (pick up, drop, etc.)
Now (I'm in Act 3 normal, but the problem was there even in Act 2, not sure about Act 1) every time I try anything it corrupts the file and it fails to load both on D2R and on GoMule. It also straight up hangs GoMule, using all my CPU in the process and I gotta end the task with Task Manager. I tried making a new character and picking up and dropping what would normally corrupt Scourger but it all works well there. Something changes along the way as you play I guess? Not sure. Very hard and tedious to test. I'm attaching the .d2s file that works. Then try to handle anything, it'll crash (even picking up an item and putting it back where it was). Please help.

My D2R classic character (act 1 normal) was corrupted after opening it in a fresh GoMule project, moving some items to a new stash, and saving.
version: GoMule R0.44
