Hello, I'm very new to KSP and RO/RP-0. I don't know where to ask but I updated "Custom Barn Kit" today via CKAN. When I've started my career, my facilities were kind of messed up. I can accept only 2 contracts down from 3 and the Action Groups button is gone too. I tried a new career and there are still no action groups available in the editor. I wanted to do this Tutorial and it suggests to use those action groups. How can I fix this? I also tried different difficulties. I guess that update kind of messed up my installation. Is there a way to downgrade that addon again?
