My base has been raided and the enemy has set up a new TC. But when I tried to destroy my former base with the remover tool, it was destroyed.
How do I set this up so that I can't destroy a wall that I don't have TC permissions on?

maybe
Use Tool Cupboards (Strongly unrecommended)
This will allow TC authorized players to remove entity within the TC range. In other words, Player cannot remove the entity only when building blocked. Strongly unrecommended means that it is not recommended to use it alone
