I am having a few issues with the combination of interstellar extended and cryogenic engines (and near future) cryogenic engines adds hydrogen for their engines thus giving the option for lqdHydrogen+oxidizer in the fuel tanks. This seems to work when i install kspi-e i now have lqdHydrogen and LqdOxygen as an option for my tanks but not lqdHydrogen+oxidizer ... thus rendering cryogenic engines a bit useless. can anyone recomend a fix? Adding LqdHydrogen + oxydizer as an option? Modding the cryogenic engines to take LqdOxygen?
