I switched to KeeperFX for the grafics and bugfixes, but it seems, as though KeeperFX is working with the old crappy AI.
I was playing from the start again and the enemies would only wall themselves in, whereas the enemies in the GOG Version with the Deeper Dungeons AI were pretty aggressive.
Also with the newest nightly, 1826 I can't pick up the 4 starting Imps from the panel, switching back to 1821 worked for me.
Any Ideas on how to fix the AI?
KeeperFX does not work with the old AI, in general it should be better.
The latest nightlies do indeed have problems. The very latest, r1826 has the issue with the imps you are describing, but the builds before that also have some other serious issues, like Tunnelers that can breach your fortified walls or imps that can pick up specials from anywhere.
As there's been no development on KeeperFX for a year, and no signs of this changing any time soon, I've compiled a release with all the buggy/unfinished taken out and the functional features in. I've also reverted the creature changes to original and fixed maps that no longer worked because of AI changes and bug-fixes.

This version does have the massively improved creature assignment, so Keepers will perform much better. Try playing a skirmish map and see a massive difference. They will also be aggressive.
If the AI does not perform how you want, you can make modifications to fxdata/keepcompp.cfg.
So far, everything works fine. I have yet to get to the deeper dungeons.
So if anyone is reading this, you can safely use the version recommended by Loobinex 2 posts above me without losing even the smallest bit of our beloved Dungeon Keeper experience or atmosphere. This is my recommendation, having played DK countless times and being someone who plays vanilla before trying anything else. PLAY THIS! :)
