Can't see anything in Blueprint's Viewport 4.12.5

I have made a Blueprint for a Pooltable which combines a few different meshes to build the table and some collisions for the pockets. All the meshes in the Viewport have their location set to 0,0,0 and scale to 1,1,1. In the preview scene I can see the table fine and only scaled it up to about 1.5. But I can’t find it at all when in the Blueprints Viewport. Doesn’t matter if it is in a Perspective or any orthographic views, lit, unlit or wireframe zoomed in or zoomed out. I tried selecting the meshes in the components pane and pressing F and it does nothing. I have even clicked on the the drop down arrow and reset the camera. I have added new components (such as a cube), and I can’t see that either. Please help :frowning:

Could you maybe zip the blueprint and post it?

This looks like a legitimate UE4 bug

Not sure how to do that sorry. I went to migrate it but it’s connected to many other things within my project which would be taken with it.

i have this some problems 2nd time i had it i thought i must of caused it from migrating bps from one to another so i remade this and it happened against here is link of bp Dropbox - skeeball001.7z - Simplify your life
