A client patch (for some graphics and movement stuff, not related to TC) just got released, though - and a patch for UOAssist.
I hope the UOAssist patch was related to the client patch, instead of it being REALLY bad timing (imagine tug releasing a patch, then having the patch broken minutes later by EA releasing one...)
OMG, looking at the patch notes for UOA, that may just have really occurred for some people (mine appears to be working right, though)
