This one has got to be one of the more frustrating ones.
Alright, so, I was doing a Minutemen side quest, and I got full on junk items. I usually gather as many as I can in case I want to fortify my base with something. Well, I went to the Castle to put my junk in the workshop storage, but it won't let me access it. I can't even access containers I placed down or ones that were already there. Did I overload something with all the stuff I put into it? Is there a limit and the game is trying to tell me I have too much stuff?
