We have a bridge including some virtual interfaces and an interface named “unknown” in Winbox. In the Terminal the “unknown” interface is named *12.

*12 (or any other number after asterisk) is pointer to object (in this case interface) which doesn’t exist any more but wasn’t properly removed from bridge prior to destruction.
