Thank you for the thorough explanation. I may have stumbled upon another solution (probably not proper though). I reset my game version to 1.12 from 1.8. instead of clearing CKAN for a clean install I simply tried launching it with all the same mods and it seems to be working fine. Thanks again for your help.
I found your mod via Mike Aben's playthrough and would like to try it, but am having difficulty. Using CKAN it's telling me that your mod is not compatible with 1.12 / 1.11 / or 1.10 due to Celestial Body Science editor not being up to date past 1.8 I am new to modding and have been unable to find an explanation.
