I copied over the Kerbalism folder and started up game.
Loaded my newly started game earlier today. Clicked on launchpad and selected to launch a craft.
Clicked on recover and once into overview all buildings seems to be lvl 3 and non-functional.
KSP.log
and
output_log.txt
EDIT: After making the log files the bug persisted after removing the Kerbalism folder, restarting the game and loading the save game.
After making a new career again afterwards it worked fine. Then tried adding Kerbalism folder again to check and same problem.
