I am a man of a loving heart. I love peace, so I decided to play a match.
It was a battle that had a deployment phase. When the map loaded I began moving my units. I dragged them outside the invisibility field. They dissapeared.
I just closed then opened the game. The usual thing to do when something is odd. When I came back, I had half my army gone...
The ones that I dragged out of the invisibility field where still there, mostly cav. But there were units missing
P.S. I lost at the end, but I managed to make his units go on a massive rout
