Warriors has an ability, when downed, that is named Vengeance that lets them come back to life for a limited duration (10 seconds, not quite sure).
The ability have costed me about 1.5 gold extra in repair costs.
If you die in Vengeance mode before the 10 seconds are over and return to a waypoint, the Vengeance mode will still be active. So when the time is up, you will end up dying twice instead of once.
It’s really annoying and have costed me quite alot of cash, hope that you can do something about it.
