[16.39] Unexpected error crash during multiplayer

[hackguy]

During multiplayer game randomly crashes, sometimes while downloading game, sometimes in the middle of the game.
Usually paired with "Server not responding" showing on the screen.
I'm using 2 mods, RSO and Clusterio (a part of Clusterio 60k event).
The crash happens pretty much randomly, as long as I'm connected to a server.

EDIT: Added another, smaller log file and a screenshot of error message.

You need to update the game.

Thank you for your reply!
Sadly the whole cluster is not going to be updated until a relatively stable version comes out (see: train problems with 16.40+).
