Currently the tc does not get destroyed with the building block. I have seen many floating tc's in the past. I assume that's what this is. Be nice to have it not print to log.
The "server log" is filling up with theses messages. I'm a server admin and was viewing the logs when I came across a ton of these messages filling up the log files and making it annoying to go through. They continue to print as we speak.
My console is getting spammed with this message: "11:00:03) | No building for tool cupboard!" Can you please make it stop? lol
As far as I know you can't destroy just the lock
