I don't know if it's the growth os the chorus plant that crushed the game or the fact I played on the snapshot.

I was messing around with the new chorus plant.

I was trying to see how high I can grow this plant, so I've updated the gamerule RandomTickSpeed to 100 to make the plant grow faster.
I found out I can put more chorus flowers on the existing plant and make it taller.
When I grew the chorus plant to about 70 blocks tall, the game crushed.

This is what I did:
1. Put an end stone on the surface.
2. Used the Command "/gamerule randomTickSpeed 100"
3. Placed a chorus flower on the end stone.
4. Wait for it to stop growing.
5. When the chorus stops growing, place a chorus flower on one of the higher branchs of the chorus plant.
6. Did steps 4, 5 and 6 untill the game crushed.
