Huge thanks for the info! I'll try to figure out and solve some of the issues you brought up. Besides that; here's my log, I made sure to have ksp closed while obtaining it this time https://www.dropbox.com/s/f0oimubve5eqv0k/KSP.log?dl=0
Whenever I start up ksp, tweakscale is not able to scale any parts, this is the warning message that I get upon loading the game. My tweakscale version is v2.6.7, and I had it installed through CKAN.
