I know this isn't a bug, but I don't know where else to post this. I reported it in-game, but I don't know if it'll only affect one person.

Sorry I'm really new. I have made a screen shot of this, but I can't figure out how to post the screen shot here.

Additional info:

Hundreds of characters spawning quickly, with random letters as a name. Royal Plantations in Central Thanalan is where I saw it. Jenova. at 9am 2019-06-12. X22.8 Y26.5
They all left as of now, but just thought I'd let you know here as well.

Let me know if i can provide any additional information. The in-game report I sent has an example of a name I saw.
