Been playing Nehrim the last couple weeks after discovering it on a recommendation, must say this is a really great effort, hope the team gets to make some money from similar things in the future if they so wish
I have one problem though
So I installed Patch 1.1.1.1 today and was set to play, but turns out I have some major performance issues suddenly

Nehrim has been running strangely, compared to normal Oblivion, but I figured it was just due to the new scripts and such. But the location I'm at now is apparently horrible for performance... It runs fine if I do nothing but just run about, but as soon as I cast a spell or create any light effect, the game slows to a complete crawl. It becomes unplayable for the duration of this effect, and the moment I get attacked by monsters, light effects happen all the time.
This means that I cannot fight the monsters present there and I'm now at a dead end

I thought at first it was related to other business, but it's not. I tried teleporting away and casting spells/create lights, it worked fine, no problem. I waited at the location and cast spells, still the problem. I teleported away, waited there and came back during a different weather, and it still didn't help. No idea what to do here... just stuck now

no idea if this patch was the problem or if it's something else... I was not at this location till now.
Location in question is this:

Anyone experience this problem or know how to fix it? :S
