Corpses usable repeatedly for Revive - Rathma

This has happened a few times during Greater Rifts -

Using a 5pc Rathma with RoRG in cube,
At the very beginning of the run, the first batch of kills is re-usable for purposes of revive. After using revive, the corpses don’t disappear, and are able to be revived again, with seemingly a random monster revive resulting in the minion ‘army’.

It only seems to happen for the first batch of revives, after 2-5 attempts the corpses finally disappear, and after any subsequent use of revive, the corpses disappear as normal.

Is anyone else running a Rathma set able to dupe this?

This was introduced with the last patch.
