Some names don't work using /ao

I get "no player found" with normal names typed sometimes.

Really nothing special here regarding strange keys or anything.

But some players cannot be found.

Could this have something to do with Clans or Better Chat?

Pay attention to upper and lower case or use the steamID64

@realedwinI did pay attention to that. It's just that some names don't work.

Hello, What does "some names" mean? Can you give me some examples of these names?

Please let me know if you are still experiencing this problem.
