Click too fast = Crash every time and other UI issues.
I've been using auto-turn but I'm kinda getting sick of the UI getting dragged away from me while I'm still trying to build improvements or units. If I click at just the wrong time to try build a second unit the game will ctd. Every time. It really needs to allow me to press 'Done' on the build menu before advancing turn.
Also as I use a mage type Sov for most games I'm finding I miss the utility of being able to double-click through spell casting dialogs in the same way other dialogs have been enhanced. But this brings another UI problem, double clicking is badly implemented, the second click always hits whatever is under your cursor when the dialogs close, that's very user unfriendly and sucks to keep track of so you don't make a mistake that costs a reload.
