I extracted CharTitles.dbc with MyWarCraftStudio, changed few title names and created new MPQ archive with only this file.
I got this error:
This application has encountered a critical error:
ERROR #131 (0x85100083) File Corrupt
Program: E:\World of Warcraft\WoW.exe
File: DBFilesClient\CharTitles.dbc
I tryed every single DBC editor i could find - TALIIS, DBC Editor, DBCUtil etc. Nothing helps.
ModelEditFix doesn't help too.
