This is more related to having them as first or second boss. In any run of the normal instance, once you kill all 3 of them the cogs pop up and you pick your shield or weapon, go back to the statue, etc. In elite after you kill the Satyr Bard and any two of the three Satyrs the cogs will pop up and allow you to choose one... except that the fourth enemy will still be trying to kill you. If you select a shield (my run) or weapon the cog disappears as normal... but then you kill the fourth one and the cogs light up again allowing you to choose again. The bug is that it waits on a count of 3 kills... despite there being 4 enemies to kill.
