From 0.99 changelog:
Fixed a bug where units would play their death animations twice (yes, we get it, you died. We aren't handing out oscars here, get on with it)
I am seeing a lot of this in 1.0 campaign while using the Mace of the Veldarii (shrink of hit). If the unit is killed by the shrinking blow, it falls down, then gets up, shrinks, and falls down again but this time smaller.
A somewhat related animation bug occurs when striking a multi-figure group with the mace. Only one figure shrinks as it dies (looks pretty amusing as the killed figure curls up into nothingness), remaining figures keep their regular size.
