Terraria Meteor has been "spawned" but isn't anywhere in my game/world

A couple of days ago, I killed the Eater of Worlds and afterwards expected a meteor to spawn sooner or later. I knew that as soon as I broke a Shadow Orb that I had a 50% chance of a meteor spawning and a higher percentage each day. So I thought I was simply unlucky. However after leaving Terraria up all night and getting back on to check for a meteor, I found nothing. I have no skybridge, I've checked all 7 floating islands on my world, and checked the bottom of the oceans as well as going all the way left and right on my world. I also used TerraMap just in case I was missing the meteor. TerraMap does say that I had broken the Shadow Orbs and it also says that it spawned a meteor. But when I search the map for any meteorite item, it finds nothing. I have checked multiple forums to no avail. If you know anything about this issue, please respond.

Here's an image of my world in TerraMap, where I'm searching for Meteorite. You can see that nothing is highlighted.

Try smashing more Shadow Orbs or making a new world. This is clearly a bug, and it may be tied to your world. Sorry for not having the best answer, but this is as far as we can get.
