The project uses Steam Advanced Session Plugin and we already have our own Steam AppID. We use a custom PlayerState ingame, but the default one in the lobby. Host/Client system. Seamless travel is true in the lobby, travelmap and ingame. Sometimes we experience crashes, when servertravel. I couldn´t find the exact cause of the crashes, but one thing caught my eye. _“LogScriptCore: Warning: Script Msg: **DestroySession - Invalid player state** ”_ I believe this has something to do with the crashes. My research turned out nothing and I havent found any solutions. Here is the error log (server): * * * [2018.06.29-17.51.31:580][512]LogBlueprintUserMessages: [Lobby\_GM\_C\_0] Added PC: Lobby\_PC\_C\_2 Unique ID: 2 [2018.06.29-17.51.31:580][512]LogGameMode: FindPlayerStart: PATHS NOT DEFINED or NO PLAYERSTART with positive rating [2018.06.29-17.51.31:678][518]LogScriptCore: Warning: Script Msg: DestroySession - Invalid player state [2018.06.29-17.51.31:678][518]LogScriptCore: Warning: Script Msg: DestroySession - Invalid player state ## [link text][1] Servertravel logic looks like this: ![245817-servertravel-logic.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/e/3/c/e3c96cde749ec9c3779bc25a99ed1fe72265a5b0.png) Looks the same when travelling back to lobby. Also tried adding “?listen” to the command line, but had no effect. **Appreciate your help.** ---

Hi, I’ve been coming across the same message recently and was wondering if you made any progress. It always happens to me when I am traveling from my lobby to a new map with a different Game Mode and Player Controller and after the new Player Controllers are created. I have never experienced a crash when this happens though, the client camera stays in the map and can rotate but can’t do anything else. Hopefully we can figure this out (: Link to log ---

Hi, sadly I couldn’t find any solution or further information about this. Since you aren’t experiencing any crashes, which I do, it seems that the invalid playerstate isn’t the cause of them . Do you have any problems caused by this? For example your clients don’t get set up properly sometimes? Best regards ---

Hi, it doesn’t seem to cause any issues in my project. The crash was caused by something different. ---

Remove the “Event End Play” my issue is that the clients will search for the server and join successfully but when server traveling the clients lose the connection and call event end play and go back to the main menu, i guess my server simulation is taking too long to travel so the clients drop themselves i dont really know you should do multiple testing with seamless travel off and steam running and not running etc ---
