Hi, I've discovered something strange when importing .save (PNGtuber Plus model) files into Remix. Specifically, if I import the .save file into PNGTube-Remix and then close the app without first creating a new .pngremix file for it, attempting to open the .save file again upon restarting Remix will result in it appearing blank. No sprites will appear.
The .save file will still open like normal in PNGtuber Plus, it just won't open in PNGTube-Remix anymore. I've also tried opening a .pngremix file, and then closing out without saving, and this luckily does not happen.
My reason for not re-saving the file was because I was just using it to study how the PNGtuber Plus model looked/worked when imported into PNGTube-Remix, and I didn't make any changes to it. I noticed it appeared blank after I tried opening it again to screenshot some parameters.
It's an easy but tedious fix: Go back into Plus, reload the file, and then save a fresh version to reimport into Remix.
