I have a character named Samuel in Combat 27.
combat/add Sa=28 and got:
<FS3Combat> Sa has joined the combat as a Unarmed. <FS3Combat> Samuel has changed weapons to Unarmed. (by KarmaBum)
It throws the character into the combat, bypassing the “already in combat” check. I noticed it because I left him in an old combat, added him to a new one, and he kept getting “Baddy is not in this combat” errors.
