PacketHander isn't fully initialized

I’m doing a small multiplayer project. the project has a lobby and gameplay map. so players need to travel to gameplay map from lobby. uses ServerTravel function when host player starts game. then host player is only in gameplay map, and “PacketHander isn’t fully initialized blah blah” logs in client logging window. I want to all players are in the map. how can i solve this problem?

In case someone else met this problem. Check if you overrided BeginPlay and PostLogin in the C++ gamemode class, and be sure you call Super same functions. It solved the problem for us.

The bug is still here… It looks like fully random and is surely a bug in the EOS plugin…
