Was attempting toreplace the current C-gear skin with a new one via "import .png" into a b2 save with the 20181202 pkhex release. The program simply crashes without an error message. I had resized the image to the proper dimensions (192x256) and replaced the background with a single shade of black. I would post the image here but it's nsfw. I doubt it has any bearing but, the save is being used with an edited rom on a DSTWO.
EDIT: Attached Save
