Abyssal Power quest bug

Defeated Kuleman in its final form.
Got all loot and book.
Used book and selected final passive points. Quest complete.
Everything while in that dungeon. Did not see a way out so used my portal. Clicked on portal but nothing happened and after few seconds dc to login screen. Logged in back and im at the stage to kill Kuleman in its final form again. No loot and no passive points.
