Big Mobs

Big Mobs

What I expected to happen was smaller mobs

What actually happened was way larger mobs

Steps to Reproduce
1.Create a new world customized (that what i did)
2.Find a mob
3.Instead of being small it now big

EXTRA NOTE : This probably the same cause of Bug MC-72292
Update : It the same cause of MC-72292 , right now it fixed , hope this doesn't happen again
