I have just installed Conq. and am level 8 (yay!). The two times I have shut down the game since installing Conq. has caused the game to freeze. Save the game like usual (actual save game, not quick save Once complete, I 'Exit to desktop' The "Saving..." message appears, the game freezes, and after around 8 minutes, I hard re-boot my computer. Now, I don't have a screaming machine and I have CTD's and other issues often enough that I manually save often. But I have not had the game freeze when exiting to desktop before. For more information: Once I chose to go Conq. with this play through, I let the game sit idle for around 30 minutes before continuing with the introduction. This let all the settlements build in the background before I even went into the vault. I did not set any additional settlements to build other than the default options. I have my performance settings to Medium with build limit override set to exceed the build limit. Considering that I'm level 8 and the settlements are still at level 1, and this only occurs when I exit to desktop (I have not yet tried to save to main menu and then exit) I don't think it's typical settlement spam causing the lock up. Hope this helps! Also, this is not a show stopper. I don't mind hard rebooting at all. I got to shoot Marcy Long in the face and then snap her neck. I'm good. I'm real good.
