Defence Against the Darkness Achievement Not Working

It seems like the updated fortification stacks aren't working with this achievement. I tried with my permanent fortification champion, and didn't get the achievement. I figured perma-buffs may not work, so I tried again with an on-hit effect. That did not work either. I then leveled a new character with Cleave, using Overwhelming Odds since that's an easy way to get fortification as a low-level. And that did not work either.

If I'm doing something wrong, please let me know, but looking at previous Youtube challenge guides, this seems like a potential bug.

Same problem for me.

I used new character, level up him to 31 in 2act to use viligant strike (which grants fortify) + fortify support (to be sure that all is OK), then I kill 2nd act boss with Fortify buff and there was no achievment.

Then I re-login to my cyclone-main character 78lvl and use cyclone with fortify support, there was a lot of Fortify stucks and there was no achievment granted.

Confirm ... this achievement is now bugged ... couldn't it be that they changed fortification buff, and they just forget to adjust this achievement?

Confirm! Cant complete this achivement.

Same here. Releveled a character to be sure if its a champion bug. But its not working now.

push ... pls fix for at least next league

i know steam achievments are a pain in the *** but pls let me finish this one

Yup, same problem here also. Not working.

Ran into same issue. Fix would be nice :)

Same issue here. Looks like the new fortification stacks don't count for the achievement

Same problem. Tried with Champ ascendancy for perma fortify (Fortitude) and also with on hit effect from fortify support gem. Nothing works, even with a full 20 stacks.
