It was a tech added/renamed by AAI I believe, it unlocks the yellow combustion engine. Its probably something on my end with the mod list though but I havent really taken the time to check which combination it was exactly. Anyway I got past it using the console thanks to Solinya's tips, so its okay.Deadlock989 wrote: ↑Mon Dec 23, 2019 5:26 pm
IR+AAI is supposed to work. But if an additional mod has changed things then it's out of my hands.
What is a "high performance engine"? Do you mean the red "electric engine"? I can confirm that it unlocks properly with just AAI+IR. Its prerequisites are Steel Age, Combustion Engine and Batteries & Charging.
Thanks for such an awesome mod, im impressed with how seamless it extends vanilla gameplay and graphics!
