I received a level one Lullaby exotic weapon and its blueprint as part of the Dark Zone Edition of the game and was able to claim the rewards. The weapon doesn't seem to be upgradeable in any way, is also indestructible and cannot be sold. Considering that it is only level one it becomes useless fairly quickly. This means that my max inventory and stash size is effectively reduced by one because of a weapon that I will eventually have no meaningful use for.

Is this intended or, is a solution to this available or in the works. I understand making the weapon the lowest level and non-upgradeable but, it hangs there in my stash never to be touched again.

I would love to hear a solution or a reason for this weapon being usable in this way.
