For reproduce this bug, debug or release, just compile a clean rev, log in, and zoninig, after about 5 or 10 zoning server crash and kick you, you toon is duplicate and server display 2 players online !

No log, no more info sorry :p But I have crash EQ2TC one time and my server 3 times by doing this :p

I just tried to reproduce this and can't, 64 bit release logged on in tim deep and did /zone 1 up to /zone 33 before I gave up and no crash of the server or client. Gonna need more info before I can attempt to track this down.
