Removing KJR fixed the exploding but i was still getting crashes, moved the IR mod over to my backup KSP and it worked, the only difference being older saves ( a few weeks old ) and it didnt crash when resizing? Now when trying to move each mod over individually to find the conflict they all worked fine... Then when i moved my new save over to the backup it stopped working. I the deleted the save and tried my backup again with just the mods and no save... it didnt work.
Gonna give up on my saves and start a new ksp, gonna redownload over night and see if it work and if my old save "infected" it, kinda annoying how it was working and now i cant get it back.
Thanks for your help and great work.
