Alright, probably will seem like a dumb remark, but I have Interstellar installed and I've tried getting any of the engines to work over the last 3 days, I cannot get one engine to even turn on. I add or switch out fuels and add air intakes when it tells me to and still nothing. Can anyone lend me some insight from the lowest part on up on how to get anything to operate properly?
