Star icon in cross hairs when shooting an enemy.

I do not remember seeing this until the new update. Any idea what it is? Critical, crippling hit or another perk going off?

Do you mean a shield icon? It's to indicate the mob is invincible.

Shows with resilient (melee only kill), Imposter Sheepsquatch, Campfire Tales Alien ending and blocking melee mobs.

Was introduced around the time of the Alien invasion update.

Hi guys,
Moonman is correct re the shield!

Bu I noticed a small red star with some yellow on it and looked kinda like a shooting star in DO. Also I was damaged when it went off upon hitting mutated enemies.

I would suspect that it is a reflected damage indicator for that mutation.

Rogue is correct. This is a star with a line coming off it. The same color as hit markers. Looks to be reflect damage as that was the mutation effect at the event. Where I saw the icon again.
