Hello!
Version [b][u]1.2.1.0[/u][/b] is now live!
This version has a new system in place to provide faster Save/Load times.
Unfortunately, this means that your older save files are no longer compatible.
[h1]IMPORTANT[/h1]
If any issues occur once the update is complete try to clear out the [u][b]SaveData[/b][/u] and [u][b]ActiveData[/b][/u] folders located in your [u][b]Buildanauts/GameData[/b][/u] directory.
