Online Players Sign

When signs are confirmed not working when using the command /opsverify they are removed.

I have now tested VanishNoPacket a bit more and it seems to be removing you from the list too. If anyone knows how to detect vanished players please tell me. I also ran into another bug about the counter showing two players when there only was one player online (which was vanished) just after another player (not vanished) had disconnected.
