It happened on a 'just started' fresh new game.

I clicked on an empty space of a map, and a special tile appeared on it.

Surprised, I clicked on an empty space right to this space, another special tile appeared.

Amazed, I did this one more time - another special tile appeared.

Now believing this was a bug, I switched to Jing and made a capture.

When I alt-tabbed back to Elemental, the bug didn't repeat itself. I still cannot know if this is a graphic bug (existing invisible tile that appeared on clicking on it) or a starting game bug, but three tiles in a row (and so close to each other) seems odd.

I have also uploaded the dumpfile (below) for this thing.
