I see, I thought it's a bug because the shelves can be full and you can't get rid of the item in order to fix the shelves. In other words, you can get stuck and wait an unreasonable amount of time, or maybe permanently?
There is a garbage to free your hands, but that's absolutely not obvious. I think next time I'll introduce mechanics a bit slower, but that's also a challenge to keep people entertained enough to stay until the end
