Not at all sure if you know this already or not but on the new 1.2.1 version of KSP the extraplanetary launchpads mod doesnt quite work as it should.
instead of there being rocket parts to construct the rockets on the launchpads it is asking for materialkits and specialised materialkits, and i am not quite sure why this is but if you want i can give screenshots, i have a lot of other mods installed on the game save in question however it shows as incompatable from the launch menu. Again not sure if you know but just trying to help. Thanks for all the good work
