Boarded "friendly" Crewships shooting invulnerable heal clouds

[Karonuva]

The crewship also shoots these out even if there's no enemies in either turret or on the ship at all, and these heal clouds apply to enemy ships and seem to never go away even when the cloud dissipates

The same happens to me, but not necessarily involving the crewships. For me there's always like 3 or 4 enemies that keep the healing cloud effect and become invulnerable for the rest of the mission whether or not they were in a healing cloud in the first place :S. 

So far it happened in every single veil proxima node i've played. it kinda ruined the experience for me, enemies are already tanky, having to deal with an unintended invulnerability makes it way worse.
