Need a vet!

Some of my animals Pigs and Cows will intermittently "freeze" until I shut the game down and reboot, so one assumes this is a memory issue, noticed this behaviour on another map and just assumed it was the map but now I am seeing it on other maps? Has anyone experienced this issue?

I know it's not my pc as I have a high end pc. So can only assume it's some of the newer maps or I have a mod that is causing issues.
