The boss also doesn't wake up when you disturb after a kill https://i.imgur.com/R3iOGiM.png
Thank you. We believe this is an unintentional bug with an engine fix we put out this week, so we're going to be rebooting the game soon to resolve the issues that arose with today's game update, this should resolve the one you reported too. The usual 30 minute in-game countdown timer will precede the reboot.
