If your client isn't in English, the auto translate of "Take care" isn't used as a farewell salutation but as a warning.

Correct use of the autotranslation:
Casting spell. Repose. Take care. Please don't attack.

Incorrect use of autotranslation:
Thank you. everyone. See you again! Take care.

For fear of this becoming the next <|cap|> of FFXI... DON'T LEAVE YOUR PARTY SAYING <|Take care|>
