Now a question for Emma what faction is Vilja in? Has this could pertain to How MMM assign it Wounding/Fatique Features ?
She is in Mages Guild, Fighters Guild, Knights ofthe White Stallion, Knights of the Thorn, Player faction and in her own faction.
Note however that Brozly has the same problem with *every* companion, not just with Vilja!
The main things that will dictate how Wounding affects Vilja (and indeed all potential companions) are the initial aggression and confidence, at the point at which the player first enters their starting cell (Bloated Float for Vilja). This is because the type of Wounding that is applied is determined when the player first meets the NPC. Whether the NPC is essential or not at that point is also relevant. If Vilja's initial aggression is 5, for example, she will be considered to be a normal non-hostile NPC, and so will get the same type of wounding as regular citizens. As an aside, the only NPC factions that affect the type of Wounding that is applied are the Blades and the Mythic Dawn.
The 'falling on their face due to negative fatigue' issue that CorePC alluded to is, I think, caused by the way Wounding works on leveled NPCs. When the PC levels up, all leveled NPCs that are not in loaded cells are immediately adjusted. However, the calculation of the NPC's new health is completely screwy (and I suspect the same is true for their magicka and fatigue); rather than calculating the new values correctly, which it doesn't do until the NPC is in a loaded cell, the engine seems to apply a calculation along the lines of (current health) * (new level) which results in Wounding getting confused, because it stores the new base health, and calculates how wounded they are based on that. Assuming the same is true of fatigue, this would lead to a rather large penalty being applied to fatigue when they are wounded (or rather, when Wounding thinks they are wounded).
This can happen to vanilla, OOO, and MMM NPCs and creatures even if you don't have Extra Wounding running, as the same wounding effects are applied through the base MMM and FCOM plugins. However, Wounding (and the resulting issue) won't affect Vilja or other companions unless you are using Extra Wounding. Therefore if Brozly or anybody else is seeing this fatigue issue on Vilja or other custom NPCs without Extra Wounding loaded, then it's something else entirely that is causing it.
And as CorePC said, where this issue
is due to Wounding, it's fixed in the next version of MMM, as I've completely rewritten the code that handles how Wounding reacts to leveled NPCs leveling up.
