I don't know if its the game for sure but its strange...

I'll be starting a scenario and all of a sudden whereever my aimpoint is it will be as if the hand of God ordered my men to go there.

Then... I'll have my boys at a door ready to enter and for some reason the game cancels my set up and orders them to return.

How about this... I actually saw my rules of engagement change without me ordering it.

You don't mention which platform you are playing on, but on the PC, your action button will order your team to where ever you have your cursor.

It has to do with the new patch (1.02). Other users that upgraded to the latest patch are complaining of the same thing happening. Below is the official feedback thread for the 1.02 patch. You may want to post there for better results
