It's really stupid how they give you this huge open world to explore, littered with all kinds of collectables, crafting materials and rare items and a nice big Keep but you can't have a single chest to store anything.
Seriously, how do they miss this? The game is generally real good but you have some absolutely bone headed oversights that I just cannot imagine how they weren't acted on while the game was still in development.
What makes the lack of a storage chest especially annoying is that on PC at least the inventory UI is terrible. So now I have to spend even more time in that dreadful menu system just to manage my inventory when just having a crafting reagent chest would do wonders.
I remember this was also the case with Origins but a cool developer just released a mod he made to add it in the PC version. Alas, with no mod support for DA:I we're stuck.
