I don't really think that you should be closing valid threads because I mentioned refund?
Ubisoft have a terrible track record, and using the excuse that "it happens to everyone, so its ok" is a little lame. Why would we be happy, that Xbone and PS4 and PC players who bought on UPLAY can play, but steam users can't. They are game developers, they are supposed to test these things before launch, or at least allow ample time for errors like this to be resolved.
They should have thought, lets launch when Valve HQ are in normal office hours and a bit early cause the beta is only 48 hours, incase we get any problems, but now they leave everything down to the wire, its not acceptable, that they say 100% beta access, then leave us stranded, people have scheduled time out of their work and life to play and ubisoft just let us down.
