HoI 4 - [1.5] Can't find a valid path on whole front lines out of nowhere

Description of issue
[1.5] Can't find a valid path on whole front lines out of nowhere

Game Version
1.5

Enabled DLC
Together for Victory,
Death or Dishonor, All of the above

Do you have mods enabled?
No

Description
I set up a front line(, the war breaks out) and suddenly all my units get the flag "Can't find a valid path". The only way to resolve this, is to move the units to another province and back again.

Had this with the German Junta and with Chinese warlords (with them even without any war).

Idk if a save or screenshot is really necessary for this, because it's very easy to reproduce.

Steps to Reproduce
- set a front line
- wait
- the problem appears after some time

Hi, are you sure the invalid path isn't because you had offensive orders active when the front was not an active war?
Otherwise I see no reason this should happen and can't reproduce the behaviour.

I can confirm, that this was the "problem". Idk, how I couldn't connect it to this yesterday. I could avoid this now most times, but sometimes (very rare) it still appears, although the path is clear (2 or 3 provinces away).

I also encountered this issue also placed front lines with offensive plans would disappear even if units were executing the battle plan

If either of you have a save that reproduces this I'd be interested to take a look
