Me and few friends have been having problems with the game since we recently downloaded it and the game fails to read files constantly and gives us error screens that crash the game. I suggest the developers should look into handing out fixed versions of the game, when I played here 2 years ago things like this never happened.
I have not play WOW about 3-5 months,The game was on my External HDD and have no problems with that to play, now it's on my PC,i play the wow on this server about 8 years without any problem ,after few days this happened ( https://i.imgur.com/xVorJJ9.jpg ) just in ''Alterac Valley'' and ''Isle of Conquest'' i tink,what should i do now? Pleas Help
There is nothing wrong with the client (at least the old one). If it's happening in battlegrounds, it might be related to cross realm features that are getting implemented.
Critical errors could happen in bugged places. I had them in sota or in the house of Valiance Keep, but it's not that they hand you corrupted data, it's maybe a little failure in a data (not correctly written)
You could alternatively download a wotlk client by another organizer and change realmlist in your config (WTF-folder) to look at improvements.
