mmccolga posted a topic in KerbalEDU MissionsWe're using KerbalEDU for an informal STEM program. We're using the first 5 missions for our 6 week class. We just finished EHC3 and we're doing EHC4 this Saturday. We're having a problem with EHC and EH4 allowing us to launch from the launchpad. The buttons at the top become greyed out and you can't launch. We tried starting a new game and that doesn't work. One workaround is to do the mission in the sandbox. We can run it from there. Then when we go back to the EHC mission, it works again. Is there an easier way around this?
