Hi, for some reason it seems like it thinks you need the Delete Rename window (you have either Show Delete or Show Rename enabled in the plugin parameters) but that window doesn't seem to have gotten created, so it is undefined and when it goes to activate that window it crashes.
I did a little investigation and was not able to reproduce this myself, so I am wondering if there is some potential plugin conflict here that is causing that window to not get created. Could you try on your end to turn non-CGMZ plugins OFF temporarily and see if the issue no longer occurs? If so, it would point toward a plugin conflict. If you are still able to reproduce with [CGMZ] plugins only, can you let me know your Save File plugin settings?
Thank you so much for your response. It turns out that it was a bit of a plugin conflict with a menu altering plugin by someone else...but this one (the save file plugin) is much more important than the menu altering one for me...so guess which plugin is staying lol. Thank you again, and thank you for all your great plugins!
