I looked into the situation and cleared everything up. It's pretty clear that Professor Eevee published their mod as re-usable with the drop dash script, and after seeing that Cman used the script, changed the reusability and then came here to call it theft.
That's pretty ridiculous, really -- permission can't just be given to make edits like that and then rescinded when someone makes edits or re-uses it in a way the author doesn't like. If you don't want things being edited or re-used, they shouldn't be marked as re-usable in the first place.
If you've marked this as re-usable and have second thoughts, you can make *all future* edits to something non-reusable (such as what happened with HORNMOD in the kart releases section), but you cannot take away permission to re-use versions previously published as re-usable.
I've given Professor Eevee a month ban over this -- hopefully they'll rethink that sort of spiteful/sneaky behavior in the future. It's pretty lame, honestly.
Carry on, Cman!, you haven't done anything wrong here.
