Minecraft – Why is the world anchor resetting

minecraft-java-edition

We just started up a new tekkit server after the last one got corrupted in a power outage and the backup was too old.

But it's exhibiting some odd behavior, particularly in regards to world anchors. They are working fine … most of the time. But if the server shuts down, they stop working until we actually go to the location of the anchor and then it starts working again.

It's not a big deal usually, but it seems to be causing some issues with my quarries where I'm getting big piles of cobblestone and dirt, which grows the longer I take to get to the area and "refresh" it and get them going into the pipes again.

Does anybody know what's causing this behavior, and more importantly, a fix?

When you shut down the server, Minecraft unloads all chunks. When you start it again, it begins with no chunks loaded, and loads chunks as players log in. Because it hasn't 'looked' at the chunks with the world anchors in them, Minecraft doesn't know that they need to stay loaded. So long as a chunk is loaded, a world anchor can keep it loaded, but they cannot cause a chunk to load if it isn't already loaded.
