I'm sure that Stardock appreciates the users going to lengths to involve the community to beta-test their software for free, but it was a sad day when game companies started releasing less-than-stable products to the community all to make a deadline. Patches should be for minor bug fixes, not major networking issues. I give them a 2 desynched fists out of 5.
Its a beta not a patch. And they make it very clear (to me it was at least) that it is not stable, and not polished. Furthermore, that is you don't like playing buggy software, DONT download it. I read that and choose not to download.
You apparently ignored their warning, or you decided to complain anyway. In either case I would suggest that's your bad, not Stardock's.
