CRITICAL! Fortification stacking bug!

[Ryethiel]

I was working on some Warlock Past Lives when I thought I heard the distinct sounds of receiving Critical Hits. At first, I kind of ignored it, because I figured it was just the Champions with their cheesy Fort ignore. But then I noticed it happening while fighting some monsters who are not Champions...

It looks as if though something causes the Passive Fortification from the Bladeforged PLs and the Guild Ship Buff to turn off. I have x3 on the Bladeforged lives(15%), combine that with the Guild Ship Buff(10%) and the Warforged Racial Core Enhancements(75%) and I should be at 100%. But as you can see in the 1st picture, that isn't the case...

The 2nd picture is after I made it back to town and re-logged. Suddenly, all was normal again. I really don't know how to reproduce this. I only know that it's there...

Monsters with rogue levels have been able to bypass some fortification for a long time.

Edit: That is completely not what you're talking about.
