In the patchlist I saw that the twin turbo setup bug on the inline 6 engines should have been fixed in either hotfix 1 or 2 on LCV4.0.
However I just designed an inline 6 engine in the year 2019. When selecting the turbo setup I see the turbine being placing on the front half of the engine (first 3 cylinders). Also there are two 3-cilinder exhaust manifolds visible were there is a turbo missing on the rear manifold.
(twin turbo exhaust manifold setup with a single turbo installed)
I am currently using build version: 200329.12268.2040.Manual
PS it also seems that the button to make the engine size arrow invisible is also not working.
I have added a picture to show the problem.
