Thanks, your config added the boiloff to procedural tanks for me. They still have the wrong LH2/LOx ratios though. Seems there's some other patch or something I have that overrides yours, adding the hydrogen option to procedural tanks even if I only copy over the CryoEngines folder (and not the cryotanks folder with the configs), giving them the wrong ratios. Any idea what that could be/how to fix it?
