Factorio Forums

A friend of mine has been having issues with trying to connect to me via factorio-steam multiplayer. whenever he joing, he connects, but immidiately gets dropped, and is presented with this error message. http://steamcommunity.com/sharedfiles/f ... 1117013845 he and i are both running the same mods, and the same version, and there is someone else who is able to play with me, so i doubt its a mod conflict, and just an issue with the base itself. any ideas?

He seems to be trying to download some 3 years and a half old map (that cannot be directly opened with last version of Factorio).
Weird stuff. maybe some log files could help diagnose what's going on.
Can you add the log files and desync reports (for you and your unfortunate friend) ?
If you don't know where to find these files, you can find them by following the instructions in this topic : viewtopic.php?f=7&t=3638, in the Provide Attachments section.

My idea diddnt work, and we are having difficulty locating those files... nothing is coming up on the search for factorio-current.log. and where the wiki said it was doesnt exist.
but then again that may just be me being an idiot.

we'll keep looking, and ill post the logs when we find them.

There must be a logfile. You should find it here :

Windows: MacOSX: Linux distributions:

Found it. here's my friend's log. https://cdn.discordapp.com/attachments/ ... urrent.log
and here's mine. https://cdn.discordapp.com/attachments/ ... urrent.log
Hopefully you'll be able to figure something out.

The game tries to run a migration script used for migration from Factorio 0.9.0, but that migration script shouldn't be present anymore.

The solution is for your friend to go to the Factorio installation directory (Program Files\Factorio\data\base\migrations or Steam\SteamApps\common\Factorio\data\base\migrations) and delete all migration files older than 0.11.0.

That seems to have fixed the issue. thanks!
