first of all when i create the content manifest files and RailVehicleDefinition files all go fine, i save them and after save they are correctly stored locally in my file structure, after a editor restart , when load my content folder all my last created files disappeared. when i create a new exact same dataset file with the same name i get an error that i have already the same file, and from this moment the file stay in my content browser also after restart. randomly the menus stay black, as example if i go to file or use right click, the selection menu flip open and stay black, it also close autmatically. i never had this issue in the normal unreal engine editors.
Same problem for route level map. Its gone when I restart editor, have to make a new route and all the content is then back so nothing is lost. I wonder if this is a part of the known saving issue. I've had this in UE4, not sure why it happens.
