Austria-Hungary defeated due to low morale, but now encountering problems with PL, CZ, and Hungary

[ironwolfpack]

To make a long story short, I've been playing online through PBME++ and encountered some rather strange issues.
In this game I am playing as the entente, and although Russia fell due to Bolshevism, prior to this I was able to advance deep into Transylvania with my Romanian forces. However after Romania surrendered and their army disbanded, I could not advance serbian, french or english units into the area of AH previously occupied by Romania: even though it was still controlled by the entente. The Albanian detachment may be immune to this phenomena but I am not certain.
I still have no idea what mechanic was at play, but trucked on and shortly-there-after, forced Austria-Hungary to resign due to low national moral. However the problem seems to have arisen again: this time although Poland, Czechoslovakia and Hungary are fully mobilised and members of the entente, they are unable to advance into Germany, or attack any of the neighbouring german units.

Seeing as it's only my first turn since AH has surrendered, is there just a waiting period to attack / advance into Germany? Or does it have something to do with Poland / Czechoslovakia being minors of Russia who has already surrendered? (obviously will take a couple of turns to get the Hungarian units to the German border so maybe they are a different story as they are a british minor).
I've played several games and haven't encountered something like this before, cannot seem to find any references to this in the manual, so am just trying to figure out what mechanic is at play here.

Did Romania surrender automatically when Russia surrendered? That seems unfortunate if they were in a strong position. Is this built into the game mechanics too?

Romania surrendered the turn after Russia signed the treaty with Germany. So almost automatic

Hi

Can you ask your opponent if they have the ability to declare war on these countries?

I wonder if this would have happened if you were playing against a human opponent. The Romanians get a relatively good deal from the Treaty of Bucharest with the Central Power, so I understand why the AI would follow a script to offer to surrender the turn after the Russians surrender. But if the Austro-Hungarians were close to collapse, a human player might wish to have the Romanians fight on. I hope the game mechanics would allow that in a PBEM game.

I am playing online, and my opponent forced Romania to resign because austria was on the brink of collapse, and Romanian forces were poised to encircle their forces and advance on Budapest.

I have sent my friend a message, he is very reliable so I am sure to get the truth out of him. Would it be possible for a minor to be fully mobilised and a member of the entente and not at war with the central powers?

It shouldn't be, but maybe something isn't quite right so it'll be good to know what your friend says in reply.

How did your opponent force Romania to resign?
