JC's heal cooldown does not always work consistently in GW.
When upgraded to level 6, heal cooldown should be 3 turns (in other words, I should see 2 turns remaining during his next turn), and initially after upgrading this ability it was like this.
After restarting today's GW this cooldown has increased to 4 turns, so I see 3 turns remaining.

I'm not sure how to reproduce this bug consistently, it may be connected to stuns, or the reason may lay elsewhere.
