Did a quick look around and didn't see this mentioned. Every time I cancel a building, let's say, to build a troop in a hurry instead, the building leaves my list, and I cannot get it back until I reload my game. Seems weird, so I thought I'd bring it up 
Also: Every time I load my game, it seems to commit the turn I was on. So, I'll save a game, and exit to main menu. When I load the game back up, I will load into the combat or event that I had clicked on, but not yet moved to before hitting save.
Having tons of fun so far though
