to help with your mis-clicks, maybe you should turn on the path preview? it always helps me, and it also looks cool
also, I think that one time where your soldier wouldn't go where you wanted him to go on the first floor of the building? I think it was because there was a soldier occupying that tile on the ground floor. I believe that's still an issue
