The recent changes ruined the plugin. People can now just get tc auth and grief your base. You should've left the option to only up/down building blocks you placed, not via tc auth

Can't please everyone. I had numerous people ask for tc auth.

yeah I had to remove it from my server. people been auth on raided base tc, /down 0. profit.

I don't get why anybody would ask for tc auth. The only benefit is to grief the base. If people are building bases with multiple people helping to build, then accept the responsibility of people being active to upgrade them if they wish with the mod. This was such a good mod to have on a server and give as a perk but now it's just a grief tool. At least consider adding both options for admins to allow, but I believe the building owner permission is better than tc auth due to grief reasons
