This seems to be the same issue as was reported in [Link Removed], as enabling net.ResetAckStatePostSeamlessTravel resolves the issue. However, it was recently reported that disabling net.FilterGuidRemapping also avoids the issue (see addl. info URL). It is possible that this is clearing NetGUIDs on the client that the server keeps through the travel.

Steps to Reproduce

In Lyra, start a listen server and client.
With seamless travel enabled, repeatedly use the "PlayNextGame" command on the listen server.
