It may just be me, but when I /zone now, the coords I land at are nowhere near what are in the zones table for the given zone, and I am standing in blackness. Happened when I just went from Antonica to Queen's Colony and back. /move 0 0 0 took me to the safe spot so I could recover.
And OF COURSE... as I am writing this to give steps to reproduce, zoning now works as expected lol... I give up. Anyway, there WAS a problem, I swear. Keep an eye out for this.

Pfft, no proof no case.

I also have this problem It may have something to do with spells loading because I don't recall having the problem before adding spells.
When the bug happens it always ports you to loc 0.0.0 but you are not actualy there and you see nothing until you type /move.
It seems to only happen while zoning like the packet to show the zone is not sent. If you logg out with the black screen and log back in the zone is fine.

There ya go. That's it, exactly. I couldn't reproduce it, but maybe that's because I did not reload the EQ2World.exe. Might only happen on fresh start? Or if it's tied to the new spell stuff, /reloadspells?

There was a problem zoning introduced a few revisions ago, if you are still having the problem let me know.
