Great game! One problem I had was items not triggering properly outside of battle if they are in storage. For example "When you sell an item" or "When you visit a store" items
I've played a few other games that have similar gameplay, they are most all like this. Something in storage won't trigger, so you need to plan ahead and move it to your main play area, which IMO is fine. Maybe just a little note on the storage, or even on the item's description tag would work!
