Steps:
1.I obtained several bathing suits from the new Moonfire Faire event.
2.After realizing several of these items were repeat items from version 1.0, I attempted to delete the items.
3.While attempting to delete the items, I noticed the "delete" option was greyed out (aka not an option).
4.I attempted to grab the previous bathing suits I had in my Armoire, thinking I may be able to delete those ones.
5.I realized that I was unable to delete/drop/sell either sets, and am now stuck with several items in my inventory taking up space that I can do absolutely nothing about
6.After waiting several days to see if the problem would be fixed, the items are still not able to be deleted/dropped/sold, and the additional inventory spaces are becoming far more appreciated.
7.I contacted Square Enix support, and received an e-mail reply, encouraging me to post my issue in the following forum.
8.I am patiently awaiting the opportunity to free up some more inventory spaces by having the option of deleting/dropping/selling my duplicate bathing suit items.
