Random extreme lag when forcing addon mobs to fight causing the game to freeze

I have a Bedrock Edition problem. When I spawn an addon mob and force it to fight it can randomly cause extreme FPS lag that may eventually freeze the game.

Steps to reproduce:

1. Create a new world
2. Use an addon that has this mob
3. Wait until it loads
4. Spawn an addon mob
5. Force it to fight something (ex. pig)

Expected results:

The game works with no problems

Actual results:

The game causes extreme FPS lag which may eventually freeze the game
