Okay okay, it's the 1.4.5, I have these mods:
B9PartSwitch, Bluedog_DB, Bluedog_DB_Extras.... here is the screenshot link: https://ibb.co/6H2Ypxv
But where can I find logs? Could you confirm me that usually, using LO + F tanks with LO + F engines should work as well as LO + H2 tanks with H2 engines?
Then Bluedog engines works pretty well on other tanks, it's the tank that are like empty?
