Describe the bug
When powering a contraption with an enchanted harvester and storage and the harvester harvests a farmers delight crop, the game crashes.

Environment
Minecraft version : 1.20.1
fabric api : 0.92.2+1.20.1
create enchantable machinery : 1.20.1-2.8.6
farmers delight refabricated : 1.20.1-2.2.4
fabric language kotlin : 1.13.0+kotlin.2.1.0

To Reproduce
Steps to reproduce the behavior:

1. Enchant Harvester (I did it with fortune 3)
2. Build contraption with storage (I used a barrel) (both rotating contraption and linear using piston crashed)
3. Plant tomato crop (farmers delight) so that the harvester will harvest it and bonemeal it to it's maximum age.
4. Power Contraption -> Game Crashes on harvest

Expected behavior
Game does not crash.

Additional Notes
The crash did not occur, when using an unenchanted harvester.
The crash also did not occur when harvesting wheat seeds, only the tomato seeds (I didn't tested other vanilla / farmers delight crops).
The crash only occurred when using a barrel (or storage in general) on the contraption. Otherwise the tomato correctly just dropped it crops.
