Whenever I switch between the VAB and the spaceplane hangar, I get an error that pops up in the top right. I've checked my KSP folder and gamedats folder but there is only one folder of Scatterer. Does anyone know what causes this? For some reason It's not letting me insert an image of the error or upload logs, so the error text is: [Scatterer][Error] Destroying duplicate instance, check your install for duplicate folders, or nested GameData folders.
