When using a line trace in the construction script so that objects can return a value destructible meshes will not return a hit. This does not affect use in game with PIE or Standalone game, but if someone is using a blueprint to place assets this can cause issues as in this case.
Edit: This issue has spread and now affects traces outside of the editor as well. When testing in 4.19 and 4.20, this occurs in launched/packaged games as well.
Results: DMs will not register a hit result in the editor.
Expected: The DM will return a hit from a line trace
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-17078 in the post.
