Minecraft version: 1.16.5
Forge version: 36.2.2
Treemendous version: 0.4.4

What happens:
When breaking a vanilla flowerpot with a treemoundous sapling in it, the flowerpot nor the sapling drops. Both just disappear.
Doesnt matter wheather you break it using a pickaxe or empty hand.
However, if you click on the flowerpot with empty hands, the sapling does drop, and you can break the flowerpot with it dropping succesfully.

Tested with the Elm and Chestnut sapling. Assuming the issue will persist with the rest of the treemendous saplings as well.

I must have forgotten to add the loot tables for potted saplings. I'm currently working on the 1.17 version of treemendous (which fixes this issue). I'll see about fixing this issue once I get around to it.
