Issue: TechReborn's Crude Storage Unit causes game to crash when broken via pickaxe or TechReborn wrench shift+click.

Reproduction steps:

1. Place a crude storage unit on the ground.
2. Fill it with any kind of stackable item (does not have to be completely filled)
3. Use a diamond pickaxe or the bronze wrench from TechReborn to break the crude storage unit. Game will crash.
   
4. The crash to desktop will cause save hiccups that can duplicate the crude storage unit and its contents when reloading.

I have also determined if the crude storage unit is empty, it can be safely broken via pickaxe without crashing.

Without Optifabric, following reproduction steps:
Crude storage unit drops as a carriable item entity with its contents still held within it (like a vanilla shulker box).
