First one I noticed is that the graphic settings were bugged. Unless you went into the files to change them it was impossible to change them via in-game. Only thing I could change was blur, AA and shading.
Second is that during the Urgent Quest there are MASSIVE fps drops during the bosses laser attacks.
Third is that some players weren't receiving items on their toon and were forced to make another to receive loot. Arguably the most problematic bug.
Anyone else notice any bugs that I haven't mentioned? The only ones i've personally run into.
