Ok, so now through finds, drops, and purchases, I have crafting items that I need to hold to to while I collect more, but my backpack is close to full. Where can I store them? I tried my bank and wasn't given that option. Ditto the attic and nothing I can see about the tables give storage. So, if you have a crafting quest that requires items galore, where do you keep them until you have enough?
If you're talking about storing reagents, then no, you can't put them in the bank.
The limit on reagents is 99 of any one type and 1000 in total. So, if you're close to the 1000 limit and you still need to collect more diamonds, for example, then you will have to use up/sell off something else (mist wood, stone blocks, black lotus, etc.) to make room.
I agree, though, the crafting tables should be able to store reagents. Either that or make it so we can store reagents in the bank.
