There are some posted issues regarding heavy cpu usage,

I think it's the same issues but I'm creating this issue as it narrows the cause a little bit.(and could be other issues)

I have started new map with update 1.7

It was all ok until I have created a farm with a villager.

It causes cpu usage 100% ( one out of 4 core), and the whole game becomes in slow motion.

That's just one villager in farm. As soon as i kill that one,

Cpu usage drops to 12% and the game back to normal.

Villagers on the iron farm or free field dont cause this.

Only the one on the farm causes it.

BDS 1.6 works ok. ( Windows7 with 8 ram)

Ok. I realized this isnt just BDS issue. It's happening to all android version so I'm posting it on bedrock issue. Plz close this one.
