I don't know if this has been posted but the game sometimes crashes for no reason.

My game crashed again, is this some sort of hack?

yes

Some threads talking about bugs and/or possible changes to CBA Hero.

Indeed they are. Some of the ideas they suggest could possibly be revisited. On top of that I don't know what has and what has not been fixed in the map. So on that note I figured it wouldn't hurt to check.

went out of sync,the first time we played

hmm none of these is fixed in cbav12 . the haystack bug is not due to units blocking the castle spawn

twice went outta sync in 4 games

I host a 4v4 CBA original game. I am told v11 isn't rated anymore. So i get the v12 map and play it. It goes out of sync once, try again, goes out of sync AGAIN both within 30 minutes game time. Everyone accuses everyone of hacking, and voobly is a much more angry place. Going out of sync seems to be a regular complaint on this thread regarding v12.

Please fix, or please put v11 map on rated again. v11 with user patch hardly ever crashes

I started a Poll to see if my experience is unique of if everyone is having it:

please vote

Out of Sync is unrelated to map version or the map itself. Just bad luck there.

Use user patch. It'll have less of an issue with freezing and out of sync issues.
