A while back I started having a problem with my current build in which repeating an action multiple times, like firing a bow 100-150 times clearing a dungeon room of undead or using the practicing method to raise a skill-example casting heal 50 times in a row, would cause a CTD and a corrupt save when saving after wards and a CTD if I moved into a new cell. I have found that disabling the KuerteeCleanUp mod stops this from happening. Not sure if this an issue with the cleanup mod itself or is representative of a conflict between mods. Just thought I would post this as may be a solution for others as well.
The Kuertee mod does perform a very useful function and I was wondering if enabling it once in a while would be of any benefit or if it has to be running all the time. TL

Are you using the latest version. I am using it without a problem, and this is my first time using it as one of my main plugins. Why not post in Kuertee's thread though?
