when I try to add a new geometry into the edit place, somehow it disappear. But if I check out the World Outliner, it shows that the actor still exist. This will happen when I keep adding new actors until it reach a certain quantity. If I try to build geometry, it’ll stop at the pop-up window of the progress bar, then the editor crashed. I’ve tried to open a new project and started all over again, but same thing happened.
I’m new to UE4, and my English is not that well. Thanks in advance.
