Okay, sorry for the holdup, but I don't have a lot to report yet. I cannot replicate this bug with the plugins I have, but that's not the entire list of plugins you have, and the version numbers are different. I'll get more plugins and later versions and try to see if I can replicate it with those.
EDIT: I don't appear to have Weapon Unleash or Status Menu Core already, I didn't see them among Yanfly's free plugins, and I'd strongly prefer not to pay for them if I'm never going to use them outside debugging purposes. Hopefully, they're not key to triggering this bug.
