Monster Hunter Freedome Unite Online Disconnect by Moving

Hey guys,

I have a problem were me and my friend disconnect on a quest.

So we see each other in in the quest hall and it loads the quest.
If we both move we disconnect, only when we both move.

We are using the latest version (1.2.2)
We did it like in this Guide (forums.ppsspp.org/showthread.php?tid=12714)

with and without adhocserver.exe

same version (ULES01213)

I tried it now for hours still crashing all the time
