Hegemon Edelgard, killed by a fort

By /u/Silly on discord:
"because as far as I can tell, fort healing works like this
AfterHealingHP = MIN(CurrentHP + MaxHP * HealPercentage, MaxHP)
but because HP is stored as an 8 bit integer, it overflows after 255"

So if you deal exactly 3 damage to Edelgard, it overflows to her having exactly 0 HP, which kills her.
EDIT: I believe this has been patched when DLC Wave 4 was released.
