[Help] Free credit glitch fix

I'm not sure how out-there this glitch is, whether it's old or new or whatever, but for those who know of the :convertcredits glitch, is there a way to fix it?

I've seen on other hotels they people have disabled the command or it doesn't do anything but I can't find the command in the db or anything to change/disable it

Sorry if this is a really stupid question lol
