Planet M.U.L.E.

I've played a few times with random low crystite with no med or highs in the area.

I've never seen this phenomenon... and I've played lots of games.  And I map out the crystite plots on paper whenever I play.

I'm not saying that you didn't see what you reported... it's just surprising that this bug exists and I've yet to notice it.

That sounds strange. Nobody else seem to have seen this. Maybe what happened is that you found a low (1 crystite) deposit beside the store but no plot next to it had any crystite. That just means that the crystite bloom extends under the store. If you supply a log file, or a link to a game where you've seen this, we can check what happened.

Or an edge plot where the bloom would extend off the map.
