Disconnected to server during corrupted nexus attempt

Hi,
It happened twice for me that i was diconnected from server during corrupted nexus attempt.
After loging, all my portals are closed, even if i still had attempts available.
The second time, i had just killed the corrupted boss and looted rewards (so quest was completed) before beeing disconnected. After relog, i had a rollback, quest wasn't completed and reward not available.

It almost frustrating that on the atlas map, nexus is away like i was failing the attempt.
So i need to find another corrupted area. My atlas tree can't progress until i find it.
