Recently, a bug has been occurring in my game. Whenever I try to make a spaceplane with the new parts added in 0.25, some of them turn into old spaceplane parts. An example: When I connect two fuel tanks to each other, the first being the old Mk2 Fuselage and the second being the new Mk2 Liquid Fuel Fuselage, when I put the structure on the runway, they have both become the Mk2 Fuselages. This is a very annoying glitch. Have any of you encountered this glitch? I hope you can help me. (Also, if this is posted in the wrong place, sorry)
