I also had the Cobl error message. The mod seemed to change my stats (Actually it looks like it canceled some of the changes that Cobl makes) so that some of my handmade spells no longer worked (Insufficient rank to do some spells)
There is a conflict with The Elder Council mod since the cave you go to is on top of the city of Arenthia. In the final dialog I heard voices from NPCs in Arenthia alongside the voice acting from the mod and upon exiting the cave at the end of the quest, I was stuck behind invisible walls.
The mod was very well done with great storyline and excellent voice acting. The monsters were insanely difficult however.
Spoiler The shadows were easy to kill with the special arrows (Very nice feature) but the skeletons were close to impossible with any weapon or spell I used.
And the final battle was epic and on the difficulty level of the boss in Mannimarco revisited. I have not tried alternate endings yet but the final perks for the one I did were nice. I am not sure if I will keep it loaded because I am still working through TEC.
I assume Cobl is mod of some kind?
EDIT: Blah, I just looked it up. Apparently makes Tamriel a more interesting place. Sorry, I'm kind of Oblivion Mod ignorant.
Like Miyth said before, we can't guarantee it'll be peachy with all mods, although the stat changing part is certainly weird.
I don't know if we can doing anything about it because I don't recall us doing anything that will alter anything that already exists, let alone the Player-Character itself.
We did our best to keep the mod as a mostly self-contained Eco-dome of horror and evil. Theoretically, this mod and every other mod should be peas and carrots.
Again, no guarantees though.
On to the next.
Oh snap, geographical conflict number one.
The Elder Council mod you say.
We'll be noting this. *Jots it down*
Monsters insanely hard?
I actually came across the same thing myself.
Spoiler The skellies were on god mode, I swear.
I reported it to the rest of the team but no one else seemed to have run into the problem. Maybe it just happens to character of a certain level range?
What level was your character?
I playtested on my level ~12 Wizard.
Spoiler Indeed, the skeletons shrugged off not only my most powerful spells, but also all the staves which cast spells much higher than my skill level.
EDIT: Oh yeah, I feel like an idiot. Miyth did warn everyone that this is an Endgame quest. So, if your character's not around lv24, then, like my wizard, we cannot guarantee your survival.
If you ARE level 24 or higher and can do nothing but forcefully embrace the floor, then we might have to look into it. Otherwise, I think this is intended.
Actually, even if you are lvl24+, we can't guarantee your survival. *cackles*
*Cries in front of the corpse of my wizard*
Again, all this feedback is great. Keep it up!
Cheerio.
