This would be game breaking, have you tried leaving with Steam version or using another device/phone? If not, then the problem is unsolvable and you would need to re-do your account.
I would avoid using 200x on anything that isn't L/S or monster materials. I did try 50x badges on PCD and it worked without crashing., you won't need too much of it. Also check on altema all the time when you're picking up any items to avoid this kind of problems in the future. Just avoid getting more than 50x grasta, badges and equipment to be safe.
I kinda messed up my Toto and only got a single weapon out of it when I forgot to turn it off.
