You know the drill, you see lots of this in your Papyrus log:
I've attached an improved script that will reduce the amount of these errors.
EDIT: This script fix is the final version. This version does not disable any of the script's functionality. It simply adds sanity checks to prevent redundant enable/disable methods being applied to predators. I've tested this script for many hours without seeing any errors in the logs. It's possible that you might still get the rare error, but I'd say that I've eliminated 95% of the LvlPredatorScript.psc" error spam, even with SkyTEST mod loaded (eg. 6 Jul 2013: Played Skyrim for 10 hours straight. No crashes, only 6 "lvlpredatorscript" errors in the logs).
My script is different from the method used by USKP 1.3.3. The USKP script won't fix errors on mods that add their own predators and override vanilla ones. On the other hand my script fix doesn't care if the predators are vanilla or not but will it will reduce the log spam by about 95%. So try either fix and see which one works best for you.
Just download the attached archive "_bugfix_LvlPredatorScript (v2.1).rar" and copy the DATA folder and its contents from the archive to your main Skyrim folder (merging it with your existing DATA folder). The source script is included. If you install/reinstall the CK you will need to recopy the fixed script afterwards.
Note: the other attached archive called "_bugfix_LvlPredatorScript (v1.1 hack version for troubleshooting only)" is the original "hack" version of my script fix which completely disables the LvlPredatorScript functionality. It will eliminate 100% of LvlPredatorScript errors in the logs but it should only be used for troubleshooting to determine if the vanilla script is actually causing your CTDs or not.
