Is the discord server still active, I've seen people with the same problem I have with the jotun wolf on chapter 3 but their doubts were resolved there
yes, the discord is active, the link is above the download section. to have a chance against the wolf in chapter3 you need to have on of the skills huldra3/firearms3/fastbuild3.
if you have huldra3 you need to have a potent huldra+valhalla+asbru incense.
if you have have fast build3 you need to have a drone.
if you have firearms3 you need to have couple of ammos.
not to mention medkits, rations and to use the relevant unit for the fight.
