Assuming it is meant to (unvFindObject "TK") doesn't return any destroyed StationTypes even when you are sitting right next to one.. Shipwrecks are listed as well as non-attacking objects like stargates and nav beacons/signs.
The same sysFindObject code will return the destroyed stations.
Adding a nodeID, deleting canAttack="true" and/or removing all weapons from a station doesn't affect the outcome. Nor does using the +unid or +attrib options.
This is not currently implemented.
In general, unvFindObject understands a small subset of criteria commands. The problem is that star systems are saved out to disk when you're not in them, so we don't have the data to figure everything out. We only keep a small amount of information for objects in other systems.
The destroyed status is available, however, so we should be able to implement the K functionality.
This is working in 1.8.2 so resolved. Thanks for this.
