Hey guys I have been playing ksp for some time and ever since I updated to 1.05, the new parts seem to be glitching out. For ex: The Mk. 1 cockpit. In the parts list I still see the old mk1 cockpit in the parts selection list (alongside the new one) to put on my planes, but I ignore it and attach the new mk. 1 cockpit to my plane instead. But when I load up the craft on the runway it loads up the old mk.1 cockpit. When I hit the IVA button, I see the IVA of the new mk.1 cockpit, but the exterior is the same as the old one. This same bug is persistent with the "Wheesley" basic jet engine, and sometimes happens with the "Whiplash" turbo jet engine. I have deleted and re-installed ksp 3 times now. This little problem was not present the 2nd time I re-downloaded ksp but the older parts were still in the part selection tabs. I have tried deleting the part files but it seems to not go away. Any suggestions?
