Apparently 'unlimited' storage is limited. Not sure why. But if you run out of room in vault storage, store stuff in a pack slave or horse saddlebags as they also are affected by the change and you should be able to get as much in them as you are in your Vault chest.

Be careful. The horses and slaves have a weight limit. What I did was put the smallest items in my horse packs.
