4.7 update 5, building persitant level deletes actors

this is something that only started happening since update 5, my level uses blueprints to create a city backdrop, but every time I build all levels the city seems to get deleted from the scene outliner, if I try adding a new one back in, it is completely invisible, any ideas?

Hello L04D3D,

I have a few questions that will help narrow down what issue it is that is causing this issue.

Quick questions:

  1. Can you reproduce this in a clean project?
  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?
  3. When you say that the actors are invisible, do you mean that they can’t be seen or that it is as though an empty actor has been placed in the level?
