I have a full chronos been 24 hours no achievement.

Did i did something wrong?
Or am I missing an item?

It didn't update the achievement progress thingy like the you need blablabla items to get this achievement something like that, I think you need to wait longer.

You must use the whole thing for a day or two then you get the achievement it may also take 3 days though :/

I think you're missing an item, you have 16 in your set and the achievement says you need 17. Don't know which one though

I forgot the torso....

Thanks all for help
