Alright, so i'm pretty new to Ksp but i have built some stuff like a low orbit station and went to and back from both Mun and Minmus. But since i first started my main save i have always been getting this problem with not being able to use the load, launch and exit buttons. I fixed it by deleting corrupted craft files, and everything seemed fine. But today i started getting the same problems again, and if i actually made it out of for example the vehicle assembly building none of the other buildings except from the recruiting center worked. There was no corrupted craft file, and i have followed your guide but it didn't really help. I'm in sandbox mode, so the career part obviously doesn't exist in the persistent.sfs file, but also the crew roaster has way more different Kerbals listed than there are in the progress tracking stations part. There are maybe 14 kerbal names in the progress part, and their names usually get repeated about 5 times each, while the crew part has all those names and way more but the names only show up once. What should i do?
