No V12 Turbo engines

Hi all,

I had purchased automation on steam for over a month; however, there is no option to build a turbocharged v12 engine. Is there any way to fix this issues?

Thanks in advance

V12 turbos were only recently added in the ongoing open beta. To opt into the beta, right-click the game on steam, go into “Properties,” and on the “BETAS” tab select “opebeta” from the menu.
