Sorry, it is just my weak English skills 
I run on regular UE 4.18.3 now and want to finish the application in this version. I just want to make sure there are now bugs that can glitch on the project. I have created a scene, but have not started the actual interactive part. I hope it supports 3D widgets without slowing down the performance.
Regular 4.18.3 is fine and does not have the bug last time I checked
