Way to Prevent Portals past a Certain Distance?
I'm wondering if there's a plugin or some other method to prevent nether portals (or just prevent obsidian/crying obsidian) from being placed by players past a certain distance. I want to make sure that the players don't go past the overworld border via nether portals, which I currently have by setting the world border in the nether to 8x smaller than the overworld (overworld border is a 50k block radius and nether is 6250), but that feels really small and I want to give players enough space to explore, mine, and loot. Is there a way to either prevent portals from being activated or prevent obby/crying obby from being placed past the equivalent border, or is there perhaps an intuitive way to alter/get rid of the spacial dilation between the nether and overworld (make it so, say, (1,000X 1,000Z) in the nether corresponds to (1,000X 1,000Z) in the overworld)? Or do I just have to deal with it as-is?
