Don‘t know if they chamged something but tested the table a few minutes ago and it works! It‘s because although i have Uplay Plus active the game starts with the „normal“ .exe file.
Maybe it‘s because i bought the game long before Uplay Plus was avaliable but i had not bought all the dlc‘s, so they are unlocked via Uplay Plus
It definitely started with the _UPP file last time i tried, don‘t know why it changed but I‘m happy
Nice so i can use it again and get the items i want (mostly the underworld package, looks so damn nice
)
So everyone having the same problem: Try if Game starts with the normal Game exe file (the one without _UPP at the end).
