Description (Small details that make big differences)
My port of this important fix made by ferrari365.
I actually compiled the script with the last Creation Kit Legendary Edition. The resulting LE compiled script has different size than the SE version, so something changed. Then I tested it ingame quite a bit, and it's working as intended. I made the port for my game, and now I'm sharing it. All credits goes to ferrari365 of course.

Description from the original mod: The Folgunthur boss fight features a main target (Mikrul Gauldurson) and ten other Draugr thrall teammates. The way the battle is structured is that at any point while Mikrul is still alive, he will be supported by up to three thralls. If one of the active thralls dies, it will be replaced by another one until there are no more thralls to support Mikrul.
Unfortunately the way this battle is scripted can cause it to get stuck in an infinite loop. For example if Mikrul dies too quickly or in any way that causes his health to not reach 0 (for example, from a killmove, or killing him with the console). Furthermore, Bethesda's failsaves to shut down the fight don't actually work, so it's not uncommon that it will stay active in your save forever if the above ends up happening.

This mod does 3 things:

• Prevents the fight from getting stuck in the first place.
• Restores and improves Bethesda's failsaves, allowing the fight to get paused (not stuck) if you decide to leave the area and resumed once you return without stopping the thrall support system.
• If you're installing this on a save where the fight is already stuck, it will be retroactively stopped and cleared from the active scripts in your save (Optional file).
  

How to check if the script is stuck?
Download ReSaver and open your save file in it. In the left pane expand the "Active Scripts" folder and check if you see a dunFolgunthurBossBattle folder there. If you do and this save file was not made when fighting Mikrul, then the script is stuck.
The Optional ESP will terminate the script from your save if it's already stuck. Should be relatively safe to uninstall, and it might be a good idea to clean your save with ReSaver.
