I have been playing for a while with HE and I'm enjoying the shadow mages a lot, the only issue is a bug with the mounts. In my case:
- I unlocked the horse, the unit instantly got it.
- I unlocked the chariot, the unit didn't get it and I couldn't select it.
- The mage mas wounded and after recovering it had 0HP, I select no mount and full HP automatically.
- I can't equip any mount anymore.
*No mods and game version as of today
