Asking about a strange animation problem

[Rickzzs]

I would appreciate any devs to answer, since this problem seems to be rooted in some animation manager.

In my mod "Your Hat, Abigail", I changed the anim asset of Abigail, basically packed "anim/player_ghost_withhat.zip" and "anim/ghost_abigail.zip" into a new one. And it works fine. But upon disabling it or entering another world that doesn't have my mod, Abigail just disappeared before my eyes! She's transparent even without shadow. Although I can still soothe/rile up her, I cannot recall her.

In the log it is said that "Could not find anim [appear] in bank [ghost]", but really, player_ghost_withhat does have that anim, and is loaded. Why does the game fail to recognize this asset? Anyway, the problem is begone when restarting the game. Considering so many mods playing around with anim assets, why this happens only to Abigail, or is it universal?

Now I've discovered that the game actually memorizes which asset the animation is from, and then fail to play anim because it remembers the mod's asset, and the mod is disabled. But it is not reasonable that the game has such strong memory across sessions.
