After today's templates update, my Death's Carapace is showing the incorrect number in the stack. I have 4 minions out and only a stack of 2 for Carapace, where it should be 8 (2 stacks per minion).
It was showing 8 for a while again...now it's showing 7.
It keeps happening to me as well: the permanent stacks of Death carapace given by minions with the Flesh of the Master trait on, apparently can be reduced from 2 to just 1 or 0 in the tooltip and the player UI (not sure if that is true for the actual game calculations too). In my experience it seems to happen especially during fights with intense condi spam in which minions die and get resummoned while in combat, as if the script struggled to track in real time the assignment of the various stacks of Carapace per condition inflicted.
Then again, the Protection boon given by Corrupter's Fervor behaves strangely too at times, the boon being granted by what seems like a timer that is sometimes delayed by 1, 2 or 3 seconds from the actual reaching of the Treshold... so I suspect there is some core issue with the Death Magic traitline rework here.
