Has anyone had this error when trying to connect to a server?
I'm playing on Ubuntu.

Kajanor had the same error when loading the save, but that was singleplayer and only happened with the steam version: viewtopic.php?f=35&t=27992

I don't know what causes it, I suspect old migration files but I have no idea why the game would try to run them.
What files do you have in Factorio\data\base\migrations (the install location, not the mods/saves one)? There should be no files older than Factorio_0.11 in it.
