hrmm, im getting this error now too. It happend right after i went and messed around with the eqstr_us.txt. Was trying to add some custom messages in, bad idea
.
Ive replaced the file with a backup and that dosent work.
The error appears with pretty much every line of text in-game. Only things that arent affected are Character, spell and item names. Some mob names are ok, some get the error.
Hope this helps.
PS - I havent patched to the recent eqlive patch.
