Hello, I am the author of a personality mod called Rimpsyche.

I was wondering if we could work together for a possible compatibility implementation for the two mods so that the pawn's Psyche gets saved in the stack.

I am unsure how we should go about this, but I went through your source code and it seems you mange mod-related data in AlteredCarbon side so maybe it would be more consistent to have the compatibility management code on your side.
I have in my mod defined save/load function along with data class, which I think you could utilize if you choose to do so. (Relevant Wiki[github.com])

Do you think we could work on this?
