I have the “Fresh Holly” item buff on. I am sitting on a flyin reindeer but the quest won’t let me throw the bombs! during “Bomb Them Again!”
im having the same problem,
I just did it right now,
do the 15 bombs with the normal mount, then use Fresh Holy b4 turning the quest
you will get the achiv
I had the same problem, but as Deathwingg said you just have to turn in the quest while mounted on a reindeer. Kind of ruins the fun of the achievement though
