Imps get stuck and kill prisoners on the way to prison

[elemanzer]

See attached video. This happened 6/8 times in this instance but I've noticed it on other maps as well. Sometimes they get stuck and abandon the body halfway to the prison. Might have something to do with how imps push an object (prisoner, spell, crate) away a little when first latching on to it.
