I think I'm the only one who has a problem with The Phantom of Eldberg quest

[Xenocide]

For whatever reason, a whole year since the game released and only today have I realised that I have missed out on playing the Stranger in a Strange Land and Cave of Dreams quests.

In my first playthrough I couldn't enter the lighthouse as it said it was locked. Even though you supposedly get a key from the guy in the hut (mynril or something?). And for whatever reason, I couldn't enter it again on my second playthrough (god knows why I didn't look it up). I guess I just assumed you weren't able to enter the lighthouse, because I've completed the quest without going in there.
So that's the first problem I came across that no one else seems to have, from what I've found through forums.

My solution was to download a console enabler and give myself the key. Well, that worked and I entered the lighthouse, but there is no letter to be found. I then added the letter to my inventory specifically - aha, the quest changes and it tells me to read it. So I do, but nothing happens.

Having already completed the quest months ago, I go back to the tavern where Jorund's hanging out, and spoke to him to see if there's something I've missed. I found out through the internet that the stranger in a strange land quest starts after the brawl with those two guys at the end of the Lighthouse quest after claiming reward from Jorund, who's 'supposed' to get knocked out or dies? Anyway, he's still alive and there's a conversation about those two guys that mouthed off at us, so it seems like it's a 'choice' in the game. Not that I particularly chose it.

I like choices, but not to the expense of missing a couple of quests, good ones, from what I've seen. Especially when never realsing they existed. Sorry for the long post, but hearing from someone who has had the same outcome and I'm not alone would be nice.

I wish there was a 'start quest' command - that would be helpful, why the hell doesn't that exist?

P.S Sorry for the long post
