Version X:CE 0.30HF1
Install this mod by unzipping it into its own folder in /mods/, or by using the mod loader:
https://www.dropbox.com/s/o806fvhzb0zijyy/internalRepairBug.zip?dl=0
Run the game, build a base, check to make sure that the first capacity bar is bright blue (if it is not, then that is another bug, see: http://www.goldhawkinteractive.com/forums/showthread.php/12264-XCE-0-30hf1-Issues-with-LUA-and-Mod-Loading-Info )
Exit out of the game, and remove/delete the internalRepairBug folder from the /mods/ folder.
Run the game, build a base, and see that the first capacity bar is still bright blue.
Optional: Install the mod, then delete it using the launcher's mod utilities, run the game, build a base, and see that the bar is now green again.
