I have no idea what mod that is
@Plasmaboo but the storage in a storage thing has always been possible, just causes issues and potentially world corruption from too much NBT in one spot. From what I remember there is also a set limit to the amount of times you can nest tags with NBT so that would be an issue too.
For my most recent cool discovery, Gany's End + Tinkers' Construct + AE2 is an awesome combination. Although it's really Gany's End that's the good one, it includes a new material with a special property after all that is insanely useful for mining. If you make a tool from endium, or with TiC any tool part is endium on creation, it will grant the tool the ability to bind itself to an inventory and all blocks mined or drops from mobs killed will teleport straight into that inventory instead of actually dropping. AE2 comes into it because the interface has the nifty property of counting as an inventory, so all three mods combined allow you to create TiC hammers that teleport all blocks mined straight into your ME system, it doesn't work across dimensions but it's still very useful as you can rebind with incredible ease.
