Problems with Potema Quest Part 2 The Wolf Queen Awakened

[ॐ SUBSONIC ô¿ô]

I haven't found an answer on Google or here, so I hope you have an idea, what I could do to solve this:

I just received a letter from Falk. Usually this should start the 2nd part of this quest, like "read the letter", which doesn't happen. When I've read it, I get no quest update (bc it hasn't started I think) to talk to Falk.

I can talk to him, he tells me about Potema and to talk to Styrr, but I don't get a quest marker to get to Styrr. I've found out, he's in the Hall of the Deads, but he doesn't have any quest-related talking options.

I've looked at https://en.uesp.net/wiki/Skyrim:The_Wolf_Queen_Awakened - no bug like mine is mentioned there.

My mods aren't ridiculously many, and they're sorted, "LOOT"ed and I've even done SSEedit not long ago.

Any ideas beside "consoling" this quest?

By the way, "setstage MS06 250" WOULD complete this quest and I would have the chance to buy me that house in solitude, right? This would be my last option, if nothing else would work...

[[ SOLVED ]] (i guess)

Um... I've tried it 2 more times, slept a long time, and now it suddenly works. I still got no quest marker or quest to talk to Falk, but he's now "leading" me to Styrr and I also got the key from Styrr for the temple.
