so I'm using ksp 1.2.2 RO and I'm having lots of problems with real fuels. so the first one is that the second stage fuel of the falcon nine which contains nitrogen thrusters doesn't have a option to fill it with nitrogen I have to add external tanks.
the second problem is that the Kestral engine just shows NaN% on fuel intake so i can use it. also sometimes it has all merlin engines (1A 1B 1C 1D and so on) and sometimes it only has merlin 1D+ engines. is there any way I can fix this ive tried reinstalling it many times and changing multiple folder with varying chances in success
Kind regards https://www.dropbox.com/s/d35rgyj82n2aky4/Screenshot 2018-06-21 16.35.14.png?dl=0
