Could not update account information - After Deimos mission Anomaly Retrieval

[-Guardian_Angel-]

So my friend (Stoet) and I just had finished the 3rd mother bounty Anomaly Retrieval.
During this mission we didn't had any bugs or problems, only when we wanted to extract.

When we wanted to extract, we had the notify that our accounts couldn't be updated and that it would retry in a few seconds.
Updating Account , this message had been shown various times. It would count down to 0 and then restart from 10 to 0 again multiple times.

When Stoet clicked "abort update" he got transferred back to loading stream and into Deimos without any rewards.
I on the other hand, got stuck inside the hallway. I couldn't go back into the Necralisk, neither into Deimos.
The only thing I could do was "Press X to revive", even though I couldn't revive my kavat.

So of course, I tried to abort the mission, but this also didn't work.

In the end I had to press ALt + F4 since I was completely stuck. 
0 rewards, 0 exp for both of us. So all the lvl'ing we did during our bounty including the resources + mother tokens are all gone.
