You at least need to install the firespitter folder as that's what actually controls the part switching.

My issue came down to a mod being incompatible with B9. Now i've installed only B9 and plan on re-installing the other mods one at a time to find the culprit.. Thanks for the help guys!

How do I change an item's subtype? For instance the mk2 fuselage fuel types. I've tried right clicking the item, ctrl+click, basically everything. Nothing happens. Help pls.
