Factorio Forums

Hi,
I have Factorio steam version. I play it on my home pc and on my fathers pc when I'm over there. the problem I am having is every time I am over at my father house and I try to load a saved game I did from my pc I get this message

Error while applying migration: Base Mod: 2014-01-28_Factorio_0.9.0.lua

Cannot execute command. Error: [string "if game.is_demo() then..."]:5: attempt to index field 'player' (a nil value)

Please help

thanks

Hi, on PC that fails to load the save open Factorio properties in Steam, go to tab Local Files, click Browse local files... In Explorer window that will pop up delete subfolder migrations which is located in data\base\ (or you can delete whole data folder if you don't mind redownloading lot more data).
After that go back to Factorio properties in Steam and click "Verify integrity of game cache" (again on Local Files tab).

YES!!!!!! That fixed it. I can now play on my father's PC.

Thanks

Paul
