No dice. I'd previously changed my character's current zone to see it that'd get it all working, so I got the whole "db not in insert or edit mode" thing before. It still didn't work :P
It doesn't seem to crash when it gets unknon opcodes (world.exe just goes about its business), but there aren't any other error messages. Something client-side, perhaps? I unzipped eqw and changed eqhosts.txt, but that's the extent of my modifications.
Anyway, more food for thought
