This is my official version as the original creator.
Updated version of FASA I fixed the RCS bug and stripped out all other mod dependencies like RPM and the reflection plugin. It was just throwing errors and didn't work anyways. Also added reflected materials as stock KSP now supports it.
I also removed the Apollo Command Module, LES and the Lunar Module. I didn't make them and don't own them so they had to go.
You cannot have FASA Original and FASA Updated installed at the same time. They use the same parts and names so you will get conflicts.
You can however overwrite your old FASA directory and it will fix a bunch of stuff without deleting anything you want to keep.
