I have died a few times by this but have not been able to log it, untill recently when I was able to get two examples of the bug.

A zombie of a cloud giant scout's punch maims you! It seems that if a mob is immune to crush, which is really silly, they turn on their animator. I spent ages getting one let alone three of those bastids. Seems rather gay to loose them to summoners , even though you have said it is by design, but to loose them like this is even worse. Thanks if you can look into fixing this!
