To be honest, Beta 3 is virtually unplayable for me. While it worked great for the first 25 minutes or so, it seems to inevitably crash. The sync bug that existed in Beta 2 seems to be fixed now, and I haven't encountered it in any of the 25 minute games I've been playing. The main problem is now minidumps - if they get those fixed by Wednesday, we'll be golden.
On a side note, try not to be too harsh on the beta. It is a beta after all, and the developers seem to be doing a very good job keeping up with these problems, and have stated that most crash issues have been fixed on their side. If you encounter any issues while playing Entrenchment, let them know so they can have it fixed by Wednesday.
One last tip, if you do decide to try out Entrenchment Beta 3, do not verify the install, it will break the game. This is a known issue, and a fix is available in your Sins folder if you (like me) verified anyway. The file you should look for if that happens is called "sinsentrench_post2.exe".
If you don't install Entrenchment, vanilla Sins works fine with the 1.14 patch.
