I get no error message. It must be that though, I'll try allocating everything first.
EDIT: That fixed it, now my plastic melts and works properly. It's resolved.
I'll make a pastebin when my mod has more elements. I'm planning to make bronze, a bunch of explosives and gases, maybe protons.
I said that you put bad the last argument(NOBODY_PT_MPLA), it should be elements.NOBODY_PT_MPLA
That's quite a necro...
