Obstacles sometimes fail to render for clients in multi-player games

[Colin Basnett]

Not sure what the cause of this is, though my suspicions lie in unreliable replication orders.

[Colin Basnett]

The underlying issue here is packet loss. The server will not try to re-send the replication data if the client failed to receive it due to packet loss. Fixing this will require a fairly heavy-handed design change.
