Hello, I couldn't find anything pertaining to this issue in a search of the forums, but forgive me if it's already been brought up somewhere else.
Whenever I'm in a tactical battle I have problems sometimes selecting units with my mouse. If I try to click on the model of the unit(s) it sometimes will not select the unit or it will select a square/unit around the unit I wanted to select. I've also tried click on the square the unit occupies and it didn't help. Often I will have to rotate and move the camera a significant amount to select some units on the battlefield.
Also, I'm not sure if this is related, I'll have problems selecting a target for archers during a tactical battle too. I will try to right click on the enemy I want to attack, but instead of attacking the archer will try to move to a square adjacent to the target.
This issue has actually been around for me since release, but I am running the 1.07 patch right now.
