I have tried the stock-alike config, and it seems to work fine except for hybrid engines. When loading the SABRE-M it game me a nullreference exception, stating that liquidH2 was not a resource. I tried to edit the B9 config file in Realfuels, but it has the resource listed as lqdHydrogen like it should. So then I removed B9, and the same error pops up for the Rapier engine (but with O2 this time) from the stock game. I don't know which config file it is, but one of them is trying to put the old LiquidH2 resource on those engines.
