Disconnecting during copper citadel boss prevents re-entry into arena

Receiving the same issue. The game crashed after killing the boss. The last checkpoint before the boss entrance has a bridge that is missing likely removed after the cut scene where the boss destroys the front of the dreadnought.

Copper citadel boss arena is still an issue. Can't get back inside the arena (just died after the boss WAS DEAD from some bs crap exploding on the floor with nothing to tell it was gonna happen). Can't get back in the arena to loot.

We can't get out of the arena either after killing the boss, which to me is also often annoying.

Still happening over 1 year and 1 month later!!! No fix?!?!?

I just died simultaneously with the boss, loot drops, I respawn only to find myself back on the first section of the dreadnaught and no way back to the arena. Just lost TWO FRAGMENTS, which cost an awful lot in this now broken economy.

The real question is, why is there no fix over a year later???
