Yes it a raiding server, no bases are safe. However this small change will make it so players who want to look for a challenging raid to travel to map edge and those looking to make a base they deem as "unraidable" to put that theroy to the test.

The change, ban or reduce the range of the item "Ender Marker" this will stop players from simply placing 3 points on the map around a base and never even loading the base.

The Pro's - people still wanting to use the ender quarry can set up a fence perimeter the same range of the item ender marker just taking a little more time.
This will force people wanting to make a large base to build on the map edge so the player using the ender quarry will need to load in the base fully so there's no cheese.

Con's - takes time to place a fence

if the item ender marker range is to be reduced it should be less than 16x16 to be in line with the digi-miner.
