oh yeah that might be the case!

Which hull was it for? Every hull has stun immunity.. but if you don't remember...go to garage, hulls , augments and try this for every hull until you find it.

Well I'm not sure if this is bug or not.. I was in a situation which a Mk4 (probably fully upgraded) shaft was aiming at me...and my hull was a Mk5(10/10) mammoth with 3353 armor. I had double armor and a 22% protection against shaft(eagle Mk4-2)... Here is the story : I got destroyed :/ And I reaaaally wonder why? Even if he had double damage.. I must have survived , right? If you calculate the damage and reduce it due to my double armor and 22% protection.. I must have survived. So I thought it was a bug and I'm writing this for a feedback Thank you
