Weird error spam anyone know what it is? (Not a bug I don't think)

Hello Everyone,

I have a weird question and I am not sure what is causing it as it does not happen all the time. Occasionally when I am in battle my chat window gets spammed with a error message "Unable to execute command while casting".

I understand that this is a error about trying to do something you can not do while casting but the issue is the only thing I am doing is casting. So has anyone else experienced this? Does anyone know what is causing it? It does not happen all the time. Is there a way to turn it off?

Are you using a maccro? When I level synced down I got a lot of error messages for abilities that I was too low to use. There is an option (buried deep) to turn these error messages off. If it's not that I have no idea.

I usually get it after extremely laggy fates like Svana or Behemoth where you have like a billion players in the same area trying to fight something.. I assumed it was always my fault from mashing my attack buttons to make sure the attacks registered around the lag so that I am not standing on the battlefield like a goober. When the latency issues dissipate the system thinks you are using the attack repeatedly as the system catches up.. xD

I have been getting the same issue. I thought I was doing something wrong.
