Factorio Forums

My friend tried to join a save hosted by me, and he got this error message: https://pastebin.com/pUQhhXJg

The save I was hosting previously had mods, and I've been messing with it a bit when making my own, but I don't think it should ever crash with an internal error like this.

The save: We were both running 0.16.21, the latest version at the time.

Thanks for the report.
We couldn't figure out what caused this so we added some extra sanity checks around the code that crashed. Let us know if it still happens in next version.

Hey guys,

we used the multiplayer scenario https://github.com/Oarcinae/FactorioSce ... layerSpawn

I reinstalled factorio and could not join because my game crashed after loading the map (exactly when trying to catch up).

FIX:
* Get the save game from another player on the server
* Load that game in singleplayer
* Join again
