@FreeThinker Yeah, it worked. I just had to change LqdHydrogen to Water in the InterstellarFuelTank-X200-32.cfg file of KSPI. Thank you so much! I could have done it for all the other part definition files, but I think this fix is temporary and the mods will be updated soon.

I have the save issue as cicatrix. My running mission has Interstellar Fuel Tanks X16 containing liquid fuel that are now filled with liquid hydrogen. Also the log looks similar, except that my tanks contain liquid fuel instead of Hydrazine. InsterstellarFuelSwitch OnStart part currently has following resources: LqdHydrogen;LiquidFuel I also wonder why the log says that there are two recource types in my tanks. That seems to be the reason why they are now filled with liquid hydrogen. I looked in the save file, but could not find any reference to LqdHydrogen. When I build a simple "rocket" that only contains one of these fuel tanks filled with liquid fuel and a probe core and I lauch that mission, the tank is suddenly filled with liquid hydrogen again. After that I tried to downgrade the mod step by step down to version 2.2.4 - no change. Would be nice if anyone found a solution for that
