Hey I thought of a neat little feature, a pass-through upgrade that allows items to be sorted to other nested backpacks but still needs filter upgrades on the nested packs to correctly sort them.

I suppose a pull-through that allows the restock upgrade access to nested packs would be nice too.

Or would this be too op

The Depth Upgrade does exactly this. Applying it to a Nesting backpack will allow all nested backpacks to retain the effects of their upgrades.

:O I can't believe I missed it
