While that's a really funny feature the first few times around, it gets irritating when certain items get "stuck" after a reclaim and can't ever be dumped or put away, and they prevent construction. It seems like there is a bug with this kind of thing where an item is claimed by a job, and the job can no longer be completed (abandoned fort e.g.) but the item is still claimed by a job and so can never be picked up. Somebody suggested magma as a solution in another thread, although for magma-safe stuff (which I often have tons of) that won't really help. Picking up huge stacks of seeds one at a time gets old too

I wouldn't mind of there was a way to just clear all the scattered items and do without them, but on the other hand that might make reclaim a bit too friendly.
