Abnormal disconnection after dying to xesht

Don't do character swap before portal back to hideout or it will result in character freeze for 15min.

I have two character, huntress for clearing and ranger for bossing. To keep words simple lets name huntress as A and ranger as B.

For boss encounters like xesht that has some mobs before reaching the boss, I usually let A do the clears then let B kill the boss. I usually portals out for character swaps but I forgot this time. A is left in the twilight realm and B died to xesht in the fight. I swap back to A wanting to start another run but I cannot login to the character anymore with the login screen said: abnormal disconnection, failed to join any instances.

I can log into other character just fine. Later after 15min I can relog backinto A again. I am guessing it is because I died from the boss fight and have no respawn attempt left while A is still in the boss map causing the bug.
