All the guns, units on map and also from reinforcements. I tried also my crew to leave the gun and the same situation happen, the gun is still mine and the enemy is attacking the gun until they destroy the gun.
I tried to change group of gun and add different group of the crew, but it is the same situation.
The same happen with all vehicles.
I am still checking the other posibilities, maybe too many units on the map. Don´t know. Anyone can help?
