I’m using perforce and everyone that has access the game is having the same problem, it also happens when i try to load a new map or change the default map in the project settings.
Ill post the crash logs when I get home, The only thing I did before the crash was move some objects around the map, the project was started in 4.8, No it only happens in this project, The map is procedural with roads and buildings on a flat landscape.
