I was engaging a scout with a mammoth,didnt click start combat, clicked away to my city, and righ click didnt work for anything, I even tried ckecking the controls, Rclick not working. I went on google and did a right click, the usual menu popped up

I reloaded the save and it works now, I just wondered if clicking away form combat does this

happened to me so many times, first day of playing i thought it's a feature and complained about having to click ATTACK or MOVE then left click target making it too much work. Discovered by mistake it actually works right clicking, but yeah, not always. Most of the time i still left click attack or move then left click target.
