I have not downloaded so cannot help, but looking at comments on other threads, I presume the issue comes from the fact that it is incompatible with 1.14 in some way. I have been looking through the 1.14 files to see what I want to tweak and there have been a lot of changes in the files due to the addition of new vessels, weapons, sensors, etc. Someone would have to go through the files of the mod and compare them to the ones in 1.14 to see what the issue is.
