Last week I did Palace of the dead solo.
I've completed the run solo doing floor 1 to 100 without dying and a save game that can prove that (also within the time limit)

I got the Pal-less Palace 1 achievement (1-50) instead of getting the Pal-less 2 achievement.
I submitted bug report but I didn't get any responds


Am I wrong, must I do something elso to get the achievement + title ?

Can someone help me out ?
