Issue description:

When you have cables in your inventory and an active battery [or other mod's equivalent item] charging inventory items, the cables get NBT added to them {lollipoptile_stack_nbt: {energy_stored_main_energy: 0L}}. This causes newly mined cables on the ground [which do not have this NBT] not to stack with them. After the new ones have been in your inventory they can be re-stacked, but mining several cables one at a time will cause each one to be placed in a separate inventory slot.

Steps to reproduce:

• Have a charged battery activated in inventory, or some other mods' equivalent item.
• Place some cables in world, and have some cables in your inventory
• Break the cables

Is this a crash?

no

I had a similar issue, my steps:

• Have generator blocks in inventory
• Recharge "Wireless Crafting Grid"
• Craft more of the same generator blocks (old ones will have NBT tag)

The annoying part here is that you need 36 reactor blocks to build a reactor. They MUST be on the same stack.

(Not sure about version numbers, playing StoneBlock 3 1.2.0)
