After a disconnect, I try to restore the game in the multiplayer lobby. There are some problems.

  1. Civilization is incorrect for non-host, human player.
  2. No team for human non-host (should be on my team.)

When trying to start the game, we have encountered many problems with “transferring” the “file.”

  1. How do we do that?
  2. How do we know it is transferring?

A couple of times the lobby has allowed us to Start game, however the non-host received this error:

To reproduce, we are just trying to restore from an autosave from disconnect. We can’t figure out how to get that work.
