Couch Co-Op Group Broken

Hello, there seems to be the problem if you want to Join Groups when there other Play Couch Co-Op

Example 1:
Me & my Wife Play Couch Co-Op and can join other groups.

Example 2:

Me & my Wife Play Couch Co-Op and can't join other groups who else Play Couch Co-Op.

We get the message that we are in the group, are immediately thrown out of the game because we did too much action at the same time.

Example 3:
Play solo and can join other groups play Couch Co-Op.


Hope this bug will be fixed quickly. Because groups of large to 6 people are actually possible.
