I just wanted to point out that with my understanding of the bug, your personal stash is more at risk than the shared stash. (So to be safe you can avoid storing lots of crafted amulets/rings/rare jewels in either.) Again, my understanding of the bug is that it has nothing to do with the shared stash. Diablo has a character file size limit (8K) that was basically impossible to hit before they super-sized the personal stash. The good news is us SPers can actually see our character file sizes to see if they are near the limit.
I'm D2R only and self found, so I really don't want to mess with someone elses stashes to test, especially when it seems like other people
have already been doing the testing.
