I have a fatal problem. I used UE4 to create a project in which I used the Landmass plug-in. The terrain is created using a height map made by World Creator, and the terrain editor layer is checked. Moved the terrain. The terrain is normal. However, a few seconds later, a pop-up window in the lower right corner of the screen said, "Terrain editing layer is ready," and the terrain became square.
Also, I am using the stream control computer during operation. Will this trigger some protection of UE4
