I am getting a fatal/showstopper error and it suggested I post here.
Below is the relevant part of the KSP.log (I think?) and here is my gamedata folder. I've redownloaded and reinstalled the tweakscale with no effect. I only copied in the folders in /gamedata, not in the /extras folder. Prior to this I was getting errors about multiple watchdog/module managers, so I suspect my efforts to clean that up may have broken it somehow.
Thank you for your help, I'm a bit of a newbie!
