Worse, some of those planet bitmaps are misleading. So sometimes even when I have the right colony module type on the right ship I end up with that message because what I thought was a rock planet was really ice, or vice versa.
I'm also glad I put planet space yards on nearly all my planets. Retrofitting is sooo much easier then.
(I don't build huge amounts of ships, but I find that the PSY's help build facilities much quicker.)

"What do -you- want?" "I'd like to live -just- long enough to be there when they cut off your head and stick it on a pike as a warning to the next ten generations that some favors come with too high a price. I would look up into your lifeless eyes and wave like this..." *waggle* "...can you and your associates arrange that for me, Mr. Morden?"
