Also it seems to like to spam this a lot.

Using latest version of zombie awareness on curse for 1.10.2

The server continues doing this in an endless loop. Left it running for 2 hours. Cycling back and forth between those two messages. Seems it only happens in the nether and it involves the pigman as you can see,

Hoping 77be177 will fix it, might be an edge case, not the first chunkloading issue the new feature has introduced.

What dimension was the player in during this? I assume the pigzombies were in the nether, were you as well? Trying to make sense of exactly why this issue was happening.

No more reports about this, considering it fixed.
