Oh dear mate, I wish I could follow a word you're saying (not being rude lol!) but I am way out of my depth here :d I re-read this several times trying to parse something out of it but I'm bewildered and entirely lost ^_^
LOL no worries at all. I might be able to javascript, but I wouldn't know how to make the great models you've made for this game, and I don't really know RPGM at all either.
That said, I did try to fix the plugin on my end just so it wouldn't be so messy on my system, and thought to share it here. I haven't tried it on any Windows machines, but if it works, there should be no difference where it saves. If should only affect Unix-likes with a different directory separator.
Edit:
Just in case: the contents of this zip is meant to replace the file
