I try to do this archievement , the content of the archievement is
" Slather yourself in wurm attractant while escorting the Vigil crusader "
I actually know what I should do,
I should kill a Plague Carrier Abomination that near to the end of the route before I finishing the escorting.
However, after i kill it, he did not explode and did not give out any AoE to let me slather myself in wurm attractant. Is it bugged or I miss something to do?
