Fix an invisible cat after calling it from far away

A known bug can make a cat invisible after a teleport when it was very far from you. The cat is still there, and you just can't see it.

Symptoms

• You blew the horn and heard it sound.
• The cat was a long way off, perhaps in an unloaded area.
• The cat should be beside you but doesn't show up.

The fix

1. Save and leave the world, or disconnect from the server.

2. Rejoin the same world or server.

3. The cat should now be visible next to you.

Avoiding the problem

• The bug appears when the cat is too far away, so call it before it wanders far when you can.
• If you are about to travel a long way, keep the cat sitting somewhere you can reach easily, or take it with you.
• You don't need to craft a new horn or re-tame the cat. The horn keeps working, and rejoining is enough.
