Lighting errors and missing static meshes in editor

[Ryan_Darcey]

I recently upgraded to 4.15 and noticed these errors after updating a map and building lighting. Not sure if it’s related to the new builtdata.uasset files, but here’s what’s happening…

1. Update map & lighting on PC_A
2. Submit all files (including builtdata) to P4
3. Sync changes on PC_B
4. Note errors below on PC_B

When I load level in the editor, lighting is all screwed up and some static meshes just aren’t rendering (note yellow rectangle)

However, when I run play stand alone, everything looks perfect.

Any ideas what’s going on here?

Thanks!
