Recently I installed some mods (SVE, EVE, Scatterer). Once I installed the mods my game started lagging. It wasn't an issue at first but when I tried to delete the mods from the GameData folder, it got ugly. I wasn't able to delete them for various reasons such as insufficient permission (I'm an admin), file still open or in use when Steam and KSP are both off, and sometimes it seems like I managed to delete it, but once I check back at the folder its back.
Anybody have any tips? (I used CMD by the way)
Still a great game.
