I often use shortcut key G in the editor to show only game view objects.
From one day to the other this suddenly also hides most of the meshes that are also visible during the game.
Only newly added meshes after that behave correctly.
I then tried to migrate the project to 4.14 which resolved this problem, but there I got problems related to light building and unable to kick off Swarm, so that is no option either.
In actual game mode everything works perfectly as before.
(I checked shortcut configuration, and is still on ‘Game view’ as it should)
Any ideas?
