though I think that issue has been adressed in Discord
(esp. after that desastrous hunt yesterday)
I bring it up here too- to keep others informed, who do not use Discord:

Sog is bugged somehow-invincible, so are his sons (i guess others reported it more detailed, eg blighted brambles
and other things we saw in chat logs- we did not have the slightest chance)
pls look into that asap
Thank you
