Hi Carl,
I've read this part on your site, but this info isn't exactly true:
'Raw, Uncut tiberium can grow on its own without doing anything special to it if it has seen some travel time. Travel seems key here, as the tiberium you get from breaking space rock blocks at home doesn't seem to grow on its own. So, you'll generally not need to cut it if you got it from adventuring.'
My sim cut out every type of gem and tiberium DOES grow when I left it alone outside the house. It could take a day, but eventually it will grow mostly. Only one time it didn't. Maybe you could correct this part of the site?
