When i loaded my first map none of the test assets appeared in the camera view although in the XYZ view it stated there was items there. No matter how many times i do it, it keeps happening and it is getting on my nerves cause all i want to do is make maps and no one else appears to be having the issue. There is no fix found on the net so i hope that someone on here can help me.

Is it when you try to move the camera and such it will glitch out ? and the xyz grid? because mine does that, once i move the cam around it will lag then the camera will just stop and go to a black screen and do a weird window glitch.
