As part of our attempts to improve performance, we are temporarily altering the behaviour of overland mob artificial intelligence. The result of this is that you may see mobs teleport themselves back to their spawn points if they are pulled too far away from them.

We appreciate this may cause some disruption, however this move is vital to understanding next steps in our attempts to alleviate the lag and performance issues that we are occasionally experiencing. Please do provide feedback as we evaluate this change, and also keep in mind that this change is not necessarily permanent.
