I don't know if this has been reported but there is a visual bug when using Petrify. If an enemy dies while under this status. Instead of appearing dead they are 'stuck' with no health bar. This is easy to recreate:

1. Pick a team using Mithrala. In the screen shot I am duoing Ice Golum with Artak. 

2. Kill anyone under the debuff.

It is a bit hard to see but the minion is actually dead. It has no health/turn bar but isn't dead.
