Unable to use Simulation Meshes for the Modding Kit

[HalfMetalJacket]

I'm trying to help a friend add some cloth physics to some capes that he's made, but for some reason the cloth editor will not let me save it.

Am I not doing something correctly? Is this intentional? Or is this perhaps some sort of bug?

I believe I am on version 1.5.7 of Bannerlord atm.

Normally you get this error when you're trying to overwrite something from the vanilla game. Shouldn't be the same for already existing mods but either way try exporting the model, create a new module and import it there. Then see if it lets you save over it.
