I own the following DLC:
Celts culture pack
Longbeard Culture pack
Empires of sand culture pack
The last roman
and age of Charlemagne.
Yet when my brother tries to play on my account he only has access to:
The Empires of sand culture pack and The last roman dlc.
I have tried reinstalling the game but it doesnt work.
In the owned dlc windows the missing dlc's dont show up for my brother but they show up for me.
My brother does not own the game or any of the dlc.
