I'm making an HQM modpack and it's going great, however my pack focuses a lot on exploration and dungeons/ruins, that sort of thing. However, I don't want players to be going around building bridges and destroying walls and things like that in my dungeons, but at the same time, I don't want to set their gamemode to adventure or take away their items for that dungeon. Is there a simple mod which just disables breaking and placing blocks within a certain, customizable area? That would be great! Thanks.
