Duplicates Climbing non-existent blocks (with gif example)

I've seen this behavior many times. It seems if they have a "move to" order queued, they don't take into account that the block has been removed. I get this all the time when trying to force a dupe to dig the block out from under their own feet so they'll fall. They destroy the block, then magically float in the air for the second it takes for them to climb onto another block.
