Is the abuse of the tc restrictions possible?
For example if players decide to put tc's in front of other player's bases (Griefing) wouldn't they be able to just deauthorize and prevent using one of their tc's for that?

Hello, no, this is not by authorization, it's by ownership. So it cannot be tricked like that.

That is perfect. :)
Thank you.

One more question:
If a tc gets destroyed will the player that placed it have 1 more tc to place then?

Yes, every TC that is destroyed is not counted anymore

You created a very important plugin here.
Thank you for that.
