Annoying bug (Borderlands: The Pre-Sequel)

It is connected with the passage in the cooperative.
When I come back with another game back in, the game asks me to count my progress of tasks in another session.
I answer no because I want to get the reward for the quest itself, once again, well, or ever, if she took my friends.
And everything seems to be fine... but...
One has only to leave the game and log back on as the most cooperative progress I machine counts without asking, and I, of course, there's no reward get.
I even the contents of the chest moxie provtykal. It is insulting to horror. The bug is reproduced 100%.
