You mean there really is a problem with the patch? Besides the one error i mentioned earlier in this thread (which could have been caused by anything including the brand new nvidia drivers), I've been playing all night without any issues. Actually, my units are talking now (i think thats what they are doing cuz only the english speakings civs speak english) and i never even realized they didn't before.
edit: no, i didnt get an error while installing. no, i didn't install xfire. yes, worldbuilder works perfectly (including the fixes to it).
