The normal bonsai pot works normally but the hopping pot doesn't show animations.

Minecraft 1.15.2
Forge 1.15.2-31.1.0
bonsaitrees-2.1.0.1

Sorry, I'm personally not supporting any versions below the upcoming 1.18.1 version.
Maybe someone else wants to pick things up for older versions - I simply don't have the time.

I have the same Problem.

Hopper Bonsai show no soil nor tree nor animation.
Normal Bonsai Pots are working fine.
