Hello,
We are having issues using smooth sync since our update from UE 4.23 to 4.25.
Running with 4 players with a dedicated server on the editor and the average network emulation we had this problem on the start
and also here
I removed the packet loss emulation and it this seems to not happen anymore.
We also had other crashes SmoothSyncTeleportServerToClients_Implementation because realObjectToSync is null and then it crashed on getPosition.
