Aircraft update has been rolled out and brought some bugs along with it.
Running up to date Win 11 Pro here and latest GeForce driver for my 2080 Super yet still when launching the game the picture is split by two. One half goes to my main monitor, second to a slave monitor. Running two 1440p displays here.
The issue can be fixed running DX11 by simply alt-tabbing, and can not be fixed at all running DX12. Switching between screen modes doesn't help: tried fullscreen and window mode with no luck.
Regarding Hacienda. Not sure if it's intended like that but you can not use the Hacienda road and build a railroad across it (the road is in the range of Hacienda of course). This issue forces you to combine a gravel Hacienda road with brick road which looks odd.
