## Update Information

Hello friends!
This update contains some significant performance improvements for all players, as well as continued work on the \_Spaced Out!\_ Colony Imperatives and worldgen. Finally, a number of crashes have been fixed. Let us know if you see any other problems with the Base Game, and thanks once again for all your feedback and bug reports during this mergedown!
