I don't know what is Pokemon Go crab. Who plays these games know better. I hope this is not humiliation.
If you are a good mapper, you know how to specify the source of information. I'll tell You.
1. If you were in that place, then you need to write "survey"
2. If you used the same source and are sure that the author is not right. Write to him. Kindly, without personal assessment, he will answer.
3. If you used additional sources, write the word. Example: "natural map of ... 2017".
I was hoped that the second time you do the right way... So used reverter.
Have a good mapping and be respectful.
