Summary
Armies being deployed as invading formations automatically.Description
I think it's not a bug but poorly designed making you want to quit the game sometimes:Once an army finished defending an invasion or occupying a front, it might be deployed to another existing front automatically, including naval/land invasion front, then you can't stop this deployment unless you cancel the invasion because the game considered this army formation as one of the invading formations.
This causes the big armies often traveling across the world despite having insufficient supply network just because you initiated a small scale invasion to disturb your enemy.
I have seen my 200 infantry units trying to swim to Europe to support an invading front after defending Beijing, and naturally their organization dropped to 0 before they could cross Indian ocean, and the worst part was you cannot cancell the deployment unless the invasion is cancelled.
