Leech-Boy not hit by Stinger-Dude projectile

I was experimenting a little with hitboxes and enemy friendly fire. (related link below) and found that this guy here is not hit by his friends projectile that directly went through him.


Maybe related topic:

Addon:

apparently it is related to the projectile

Havent notice this, i know theres frienly fire and i like that a lot, but that particular situation didnt happen to me, well another thing to fix on their list i guess.
