I started playing and installed the co8 front-end. But i dont get it. I thought it fixes bugs if you play the original modul, but the looting wont work, game crashes from time to time...
If you select the original game in the front end menu, you're playing just that - the original game with no modifications whatsoever. The original game featured the looting bug (eventually). Atari patch 3 was supposed to fix it, but I don't recommend that patch as overall it seems to cause more problems, particularly with the Vista OS. If you want a bugfix-only mod (or something as close to it as possible), I'd suggest Co8 3.0.4 or the custom content removal mod done by Sitra Achara (compatible with Co8 5.0.x). Both will fix the looting bug and both can be found at Co8 here:

So i activated the mod-pack module and started a new game. Now everything works fine, but there is new content added here and there, so wtf is it with this?
If you play Co8 modules 4.0.x and onward, yes, you will be playing with Co8 added content.
Also, there is no cloud sword in the current Co8 modpack.
