Weird frontline troop behavior - WAD?

[otaats]

Okay, so i am maybe missing a game mechanic or something of sorts, but as you can see in this 1 screenshot, 2 armies have a simple frontline order assigned to them (Mengkukuo and Korea border). Instead of spreading divisions along the frontline, for some reason they are all in one tile. This usually happens in weird places (around Kashmir, Tibet, etc), but i never get to understand why. The troops in the screenshot do not suffer from lack of supplies.. It's just confusing. Anyone to elaborate?

Are you running any mods? I had the same issue a week back in a Kaiserreich game. I can tell it's not Kaiserreich in you case of course, but still, I don't know the exact answer, but i restarted my game and it was working fine again.

Are they your allies? The front assignment cannot handle that and will bunch up all divisions at a corner touching a non-allied country.

Actually yeah that's the problem, because my Kaisserreich story was a preemptive frontline against a puppet that was going to declare independence.

Hmmm, yes, in this instance they are. I think similar thing happened when i played Communist China and was readying up to attack Tibet. But i can't be sure about that. I now know it's the ally thing i suppose. If i notice this with non-allies i'll let you know. Thanks!

EDIT: Not running any mods.
