I know, famous last words. But all I'm really want to know is what would happen to Kvatch if I turn off the kvatch rebuild mod? I saw the instructions on how to turn off the mod, but what happens? and can it be turned back on? Thanks.

I'm not sure really, so until someone who knows responds you could do this:

to be safe make a backup of the save in which the mod is active. Then uninstall the mod, go see Kvatch. If everything is OK then you are *probably* safe. If not, just reinstall and go from the backed up save.

Someone reported some unverified issue about the uninstall feature. So if KR quest is already started I don't advice to remove it until the issues are verified and fixed.
