I heard that mapsat is compatible with .21. So I tryed to launch a satellite onto orbit... M game froze every 5 seconds for a split second, unplayable pretty much. I can confirm its the Sat because once I removed the part, I didnt have that problem anymore. Also, I don't have the icon to open mapsat on my screen. So, is it just completely incompatible or is there a fix or a user-made version that fixes this??? I found no dev made update to the mod, so im just assuming there isn't a dev made one.
