That's a ... bug. Or you have another mod that screws around rulesetting that does this. As the CA comes with it's OWN ruleset and so no other is recommended.
Only the main component is the mandatory one... and the patch that has also just onemain component. The others are tweaks. But as it's a total conversion mod...As of the other components, Examn's Items waz rather unbalanced mod... this one adds a rather large portion of randomized items around, it's not entirely as bad as the original version of it, but I wouldn't recommend installing this one either.
As for the others, they pretty much do what they say in the tin, so choose however you wish.
And of course you can use the Widescreen mod, if your eyesight is likes to see more than 1024x768, as you'll need this for that, but install it after the CA mods...
The main component is the ruleset, adventures aka multiple paths and so forth.
And provide your weidu.log's content(aka open the file with Notepad for example) if you want to know what's up with the above HP issue...
Yep, Jarno Mikkola. my Mega Mod FAQ. Use of the BWS, and how to use it(scroll down that post a bit).
OK, desert dweller, welcome to the sanity, you are free to search for the limit, it's out there, we drew it in the sand. Ouh, actually it was still snow then.. but anyways.
