This is likely due to the rules of what is labeled as being in or out of combat, but here are a list of weird interactions with this mechanic:
- If you are a player who is not Shiv, that has dealt damage to Shiv, Bloodletting is considered an application of damage from you, so the entire time you are considered in combat and cannot sprint or gain additional out of combat regen. However, for some reason this is inconsistent and does not always do this.
- If you buy Mystic Regen, Bloodletting seems to be considered spirit damage, which consistently applies Mystic Regen over and over until Shiv's Bloodletting finishes applying. This is appliable via both gun and spirit damage. However, for some reason this is inconsistent and does not always do this.
Easy fix for this would be that DOT damage does not consider you in combat, or dealing damage doesn't consider you in combat, only taking damage. Otherwise you'll just have to fix these weird interactions directly instead.
