In my personal experience this bug is even worse than MACL0 and PVTE01 crashes. This bug involves a player making inventory changes (be it selling characters, talismans, leveling up talismans/characters, etc.) and then the server being "unable to save the changes" and crashing. I just spent ~15 minutes moving around talismans on my characters and maxing out 3 talismans only to have this annoying bug occur. Upon re-logging in, none of the changes I made were saved and I feel like an idiot for having wasted so much time. I hope that this bug can be fixed in the near future because there's nothing quite like spending a decent amount of time tuning your characters and talis only to have all of that time be wasted and then having to do it again and hope that it doesn't crash yet again. This is probably the 7th+ time I've had this happen in the past 2 months, only this time it frustrated me enough to actually come on here and post about it. :|
