X360, Spartan assult, Company of Stranger achivement bug
[Complete a co-op mission with at least 5 different players]
First, I finished all achievement of XBONE version.
After that, I bought xb360 version of spartan assault.
I played 7~8 different players in co-op mode, but achievement was not unlocked.
When I was played XBONE version, it unlocked with same method.
So is there any solution that I can unlock it?
