Achievements do not unlock

[Kain Astaroth]

After the last update I unlocked the last two missing weapons (have 52 now), but the "Master of Weapons" achievement did not unlock. I tried to refund all weapons and unlock them again, but that did not help. Also I see in the achievement overview that only 18 of 52 weapons are counted.

I've just made a test on fresh account and it worked but maybe there is a new issue - I'm not sure. THere is a lot of people who already have this achievement.
Try refund all, restart the game and then unlock. I will add additional conditions that will check if you have all the weapons and grant the achievement when HUB is opened.

Ok, the restart did the trick, now it's unlocked =) Thank you
