Well, this has caused me to once again uninstall TMO (my mainstay) and reload FOTRSU+interiors+whichever class boat I want my really cool markings on (and yes, I'm not being facetious - I think this is really cool). But ... FOTRSU takes so long to load up, I think I'll take a nap (my other mainstay).
Unfortunately it also ends up screwing up my shortcut start and even my open folder manually start every time and that'll take me a couple of days to sort. Erg. Yes, I deleted the SH4 folder before I started the MOD changeout.
