Fixed, thanks. The patrols cannot be attacked by monsters, so once you died Takun had nobody left to fight and gave up. The patrols did not let it go: they followed it home and kept hitting it, which made it reset again every time, so they never went back. Now when a monster gives up, every guard fighting it lets it go and returns to its post, and Takun goes home at full health. Live after the next server update.
Fixed by the same change, thanks for the screenshot. Finn, Garrett and Riley are guards as well as quest givers, and they were stuck fighting Takun along with the patrols. An NPC in a fight will not talk, so their quests could not be handed in. Now when Takun gives up they let it go and go back to their spots, and you can talk to them again. Live after the next server update.
