Mod corruption problem at mod ID 42

[Castornebula]

This is a copy of a post I've made elsewhere but I'm trying to get some insight from as many places as possible so apologies if you've seen this on other sites.

 

I'm having a weird problem where saves seem to become repeatedly corrupt, but only with once specific thing, otherwise they load and play fine.

 

Any mod that comes up as the ID 42 in the load order seems to become corrupt and everything from the mod in the save is lost. The mod is still active and works right away, but the save acts as if it's gone. Trying to load the save brings up the following:

Looking at the save in Wrye Flash shows up this:

Two seperate saves from different times and locations both corrupt the same mod at the same ID.

This only seems to happen after quitting the game, i.e. saving and then loading within the same session won't show any corruption.

 

I tried deactivating the mod that was affected, but this only caused the mod below it which now took the ID 42 to become corrupted.

Is anyone experiencing a similar issue or can tell me what could possibly cause this?
