I downloaded and installed the Darkest Day mod ( latest edition, compatible with ToB) some time ago and have had a lot of fun with it so far.
However, as I am nearing the end of BG2 I am wondering what will happen when i finish that part of the game.
In the original, BG2 only mod there was another mega quest available after defeating Irenicus. Is it still there? And if so, how do I activate it ( since one is teleported away after winning)?
I'd be grateful for any comments ;)

That's exactly what happens. You disappear, and at the end of the big TDD quest you get teleported to ToB.

Must get back to working on my TDD fixpack... I keep forgetting about it.

What to expect? Bugs.

Nice answer, Rutkowski...believe it or not, it's been bug-free so far.
Alavin, does that mean I can do the TDD quest after I finished off Irenicus?
Just to get this right;)

Yup. After Irenicus kicks the bucket, off to TDD ye shall go.

I'm also one who encountered few bugs when I was playing it. I've found a fair few just by reading the files, though...

Have found one as well ( though the mod is still incredible given that this is no commercial product)...do you know what the properties of Hermolust ( staff found in the Trollfort caves) are?
It does not list them :(

What a pain; I'd ironed out the typos and fixed the scripting from every one of the 407 dialogues, and it seems I accidentally deleted them.

With that item: Are you sure you've got the name right? No item of that name is listed in the tp2 of the WeiDU version.
