Ok sounds weird. I will try something for next update but I can't be sure that it will solve your problem. OS problems are pretty hard to solve, but not impossible!
Which system have tested RPG Paper Maker on so far ?
(sorry for late answer) It was tested on only one MacBook High Sierra 10.13.6. And there were also people using macOS that could signal issues!
Great ! so you'll be able to make a fix ?
