If possess a mob that isn't in water, movement speed become extremely fast in water. Also, if possess a mob that is originally in water, the problem disappear.

What if you use the human origin? it should have no effect.

The glitch is present no matter your origin.

Thanks for the report, should be fixed in the latest beta.

Duplicate of #514 by the way

issue still present on beta 9, its very funny, but also kinda game breaking
