Is this just within so many blocks of draconis or of the ring portal in Middle Earth? I was under the assumption it is protected by default in the pack so that you don't build to near areas that will change with upgrades. Possibly you have perms as admin, friends do not, and that's what is happening?
It was at the start by the boats where you spawn when first entering the map.
My two friends tried to break barrels, and they both claim they would turn into a creeper trophies or stuffed creepers or something.
Its wasn't like that for me however, I could easily break anything I wanted.
They also couldn't open any doors. Again I could open them, but they couldn't.
It wasn't like this before. I had an old server of this pack right after they fixed the quest long not showing the quest complete thing.
I honestly wish I would have paid attention to the old update we were on. Then we could downgrade and use the old update and server, which let my friends do what ever they wanted.
