Found a little bug while I was testing with mob spawning. I spawn a squid and then I try to push it in the water. It went flying forward and zipped back. I recorded a video of this little bug. I hope this helps you on patching these up.

P.S I put the video on attachments. Hopefully you can see it.
I apologize for bad grammar. I hope I provided as many details as possible. I just wanted to help
