kirac's Vault disconnects

i've bought the kirac's vault pass and it's been fine until the final reward, now when i go to claim the last vault everytime i enter the zone it disconnects my game.

Rough. Sounds like a technical problem. Probably have a look on the bug reports section, and if you don't see a thread raise one. I have not heard of this before, but it might be a known issue.

This looks a bit similar, not sure if there is something more recent.
