Co-op not working

[denislav.parvanov]

We are trying the co-op feature but the second person is always getting an error when try to join:

The connection to your session has been lost. [0x0015]

Your connection must've been lost then.

I'm having same problem. I've got solid fibre connection ao I know for a fact it isn't my internet. Searching for a solution is also proving to be a huge pain in my anus.

Please, for the love of God if anyone knows wtf is going on let us know. I'm sitting in South Africa so not sure if physical location has something to do with it

This is why achievements should not be attached to co-op games ..
unless it's Verses ..

i understand players wanting to play together for co-op play regardless so this is an issue within itself ..

networks go down or lag in local area's for different reasons which can cause game bugs which could have lasting affects .. (achievements not popping) ..

hope your problem get cleared up soon ..
