Bug/Issue Mooshi stuck in the ship

I was using my relocator in my ship with my animals farm without problem but when I wanted to release Mooshi he got accidentally stuck in the floor of my ship.

He can't move but he continues to produce milk.

I can't capture him with my relocator again and I can't stuck another of my animals farm.

I play on Windows 10, 64-bit and I don't use mods. I was playing in windows mode.

Here is a screenshot of my ship.

 

Just take a bit of lava and you can kill it to get rid of it.
