Issue fixing is no different in the overworld, if you know where the mining area is, you can remove or edit the related region files. I've played with mining ages before, I was pondering why they were so popular. Generally the free teleport to quarries is the best feature, but I understand they're useful in other regards, I was more pointing out people's main reasoning behind a 'mining age' is flawed. The tools are there and given for you to be able to make a mining age, and as a server admin, you have to accept that you need to take the time and set up such things, or ask players to include a mod that does it for you. And you do realise that you're suggesting how others should play by asking that the modpack includes a mod that you feel you need for your server, rather than just including it for your players, right? Ofcourse this is moot if Yulife decides to add it, and strangely enough I'm not actually against that. Not that I want the mod, I just don't care if it's included.
