What happened?

When using some items notably ingots and string, there is a chance depending on their use in a crafting bench or anvil (like repairing a diamond sword in an anvil, but put in extra diamonds) and you shift click the item or pick the item out of the anvil or crafting bench some times the left over items (diamonds in this case) become unstackable with existing diamonds or unable to go back into a storage drawer. It requires items to be put into a crafting bench (if possible) and make a block of that items and then de-craft it back to its individual parts (e.g diamonds in this case). This all started once Silent Gear was added, but looking at the tags on the both items they appear the same.
