Hey guys. Here is some information that you will need, since there are time you will encounter such items.
I have mostly found this to be an equipment error, not so much anything else.
So it's real easy, now there are a few ways to 'find' these.
Mostly is if you gamble, when your game crashes randomly, because of the auto-save, you will have an 'extra' item that you can neither sell nor delete when you return in-game. Why? Because ALLSTAR failed to correctly place the delete button. What happens is when you are in the items mini menu, there is;
That's what you -see- and it should be is;
For some reason the buttons were switch, I don't ask question to ALLSTAR anymore. Yes, you lose 60 lars, but who cares, that's what gambling is.
Another way is by crafting, but this is the utmost rare chance that your game crashed as you craft. Most likely it will crash for something else besides the crafting, but who knows, I don't have the program to see W.F. codes and see the error log... (If it even has one...)
Boss(es); Yes you can get armor drops, they are Legendary, or at least the ones I've found. Besides that, the game will crash slightly more often than the crafting but still, it's the utmost rare chance.
Quest Rewards: These are usually General Grade, so ditch it, not worth time, and a waste of space. Happens more than Boss(es), but still in the utmost rare chance area.
Edit for Trax: In all "fairness" which it isn't, just 'Delete' the item by going into item's mini menu, and select "Detail". It will come up with another menu saying "O to confirm, X to Cancel" Hit "O" and viola, its gone. ^-^
Hope this helped!
