Nothing happens, but the circle around the save icon turns lighter. The save is the same as pre-editing. Although this could be because I'm on 11.1.0. It could also be because battle cats pop was updated, or JKSV doesn't work for this. I'm using a9lh.
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
