Any mod that turns a territory neutral causes you to lose control of the tank/commander/whatever unit is there.
This can crash games.
In the case of the tank mod, you lose control of the tank when the territory turns neutral, but technically the tank is still shown as belong to you.

In this case, I am using the meteor mod.
