"Anyone any idea how to make the FPSC prefabs FPSCR ready?"
Unfortunately, those prefabs are made of FPSC segments, which won't work in Reloaded. (Actually, they could be made to, but the effort made to do so would be way more than just making them again from scratch to begin with!) It's not the same as working with the entities by any measure. The upcoming conkit will hopefully allow us to something along those same lines!
Edit: And yes, glitchilly is a word; I mean, at least now it is!
