locks/init.lua:493: attempt to index field 'locks_sent_lock_command' (a nil value)

[Bastrabun]

I'm not sure what exactly the user did, most likely he tried to configure a shared locked door.

Seems like it happened 3 times at least:

These are the clues extracted from the three different incidents:

Seems like a user went on his way to craft a shared locked door. I didn't see him place the door though.

The peer was not found warning appeared several times in a row before the incident, but I do not know whether there is a connection. On the third occasion the door was most likely already in place.

These log messages appear, when someone places a shared locked door:
