I think I know what is going on ... GitHub replaces spaces in a file name with periods and it could be that KSP is having a problem with more than 1 period in the file name Thanks for bringing this to my attention ... I'll update the OP One question though, since you're on KSP 1.8.1 why not just use OrX Kontinuum ... It does all the calculations for your times as well as saves it to a scoreboard
