I've just noticed that the game data directory changed location in the last version of the game.
In Rebellion v0.62 (the one with just the TEC factions), it was inside a hidden folder at:
C:\Users\<USER NAME>\AppData\Local\Ironclad Games\Sins of a Solar Empire
In Rebellion v0.75 (the one with the Advent factions), it has changed to My Documents folder:
C:\Users\<USER NAME>\Documents\My Games\Ironclad Games\Sins of a Solar Empire Rebellion
I like the new location better, because it’s easier to install MODS and see screenshots. I just have one question: can I safely delete the files and folders from the previous location?
Edit: This is in a Windows 7 system, don't know if it's the same in other OS's
Edit: And now we are back to version 0.62, version 0.75 is no more! Until we get it again, hopefully some time next week
See this post for more information about what happened with patch 0.75:
