Both of the Don Quixote Statue points were created by the same cartographer within two minutes of each other. Here are the transaction hashes-
1st Point (unchallenged) 500 FOAM- 0x4929b35f72d36202085e16539d45f78c7cb3be560f360240e2e0c04af7849031
2nd Point (challenged) 500 FOAM-
Would be interesting to hear back from the cartographer (looks like a new one) to see if this was a UI/UX issue, where they posted a point, didn’t see it and didn’t realize that the map indexer takes a minute or two to pick it up and show it, so they added the point again.
