So in this bug what actually happens is the character body is freezed at a particular point but it's movement doesn't so for ex:-

I have a Hen and it's moving around my house and suddenly Hen's body freeze at a particular spot but Hen's still moving you just can't see where coz it's visible body is freezed and is not moving but if I kills the freezed body no matter where the hen is roaming she will die and the floating meat will be available where the hen's invisible body was at that particular time 

And when this happens it happens with all the characters at the same time like I encountered a Hen and some mobs frozen at their places but still I was getting hitted by the mob 

I encountered this three time withing 36hours after downloading beta version please fix this soon.
