Editor crashes with 2 or more Clients when spawning a Blueprint created from a Static Mesh using the Blueprint/Add Script button. Blueprints created from Static Meshes using other methods do not cause the same problem. The crash error message is:
Assertion failed: RemoteRole == ROLE_Authority [Link Removed] [Line: 2432]
Reproduced in 4.7.6, 4.8 Preview 2, and Main (//depot/UE4/Promotable-CL-2550487), though crashing in Main did not provide a call stack and crashed much faster.
