Hi there; dang, I didn't see this topic; I reckon we're talking about the same as I wanted to point out here: https://github.com/nicholasgower/planet-muluna/issues/120
I believe it's more on the Muluna side to fix this (or support this, if they want to), but I'm not entirely sure... Muluna makes a copy of the vanilla plastic, and if a mod "messes" with it before, they can't know, although they're already implemented a few lines to kinda "undo" the modifications other mods make to vanilla plastic... I'm interested how this turns out in the end... :-)
