Since the wild update, Drowned's AI on mud blocks have been weird, and no one has addressed it so I'm making a ticket now hoping it gets fixed soon.

Drowneds would start jumping when they walk on mud as if there was another block in front of them that they have to jump to. This shouldn't happen.

Steps to Reproduce:

1. Have a large patch of mud blocks on the ground for Drowneds to walk on
2. Spawn a bunch of Drowneds
3. You can either lure them by being in survival or wait for them to move around in the patch of mud
4. You will see that Drowneds will start jumping forward as they walk indicating that they think there's a block in front of them that they think they need to jump to

A video will soon be provided to demonstrate the bug at large.
