    "Serialization Error", Game crash while connecting to servers

    ( Sorry for my english, tried my best )

    Problem Encountered :
    Hola ! With a friend we tried to connect to a server , the first connection didn't cause any trouble but when we tried to reconnect later we got an error and the game crashed ( Image ).
    To make sure it was us and not this one server that was getting the problem we tried to connect to other servers, always the same error.
    Steam Game Folder Verify didn't point out any missing or corrupted files.
    Looking on the web and the forum we found people having same problem so we tried the solution they used to be able to play ( Deleting what was in `C:\...\AppData\Local\Onset\Saved` ) but it was still crashing while connecting.
    So we tried to uninstall - reinstall the game via Steam but nothing changed.

    Description of the crash : We are on the black loading script, the script get downloaded and then a little white pop up appear and say :
    "Serialization Error : Action Needed" "Corrupt data found, please verify your installation"
    If we click on OK on the pop up, it disapear and close the game and open an Unreal Engine 4 crash log window

    Unreal Engine 4 Crash Log Window ( copy pasted ) :
    Fatal error!

    Pop Up Screenshot :

    Sorry for the error.
    Do you use any pak files in your packages? If so they might have not been updated for the latest version of Unreal.


      Hola, Thanks for your answer.
      We're using Frederic2ec's 'OnsetRP' framework, how can i know what part isn't usable anymore and need an update ?

      But i don't get this problem only on our server so i don't think it can really be linked.

        Please share the server IP with me so I can test it myself.
