Hello there.
I'm not sure if it happened after my game had crashed or cause of any other reason, but some items disappeared from my bank (4 primal earths and 6 mercurial adamantites). I've noticed it just because I was gonna to level my profession, so I guess it is possible, that some other stuff disappeared too, but I'm still not aware of it. Did someone ever face such issue before?
Update: also there is an item on my bank, which was recently sold. So this is some rollback issue obviously.
