YEP_ItemCore adds mysterious weapons.

[PathosFear]

Well, I lack the knowledge to debug or even diagnose properly. It's just... A thing that happens. But if even Yanfly can't see whats wrong, and since the plugins are updated, and everything else is too... I've spent more than 200 hours on the game, I can't just give up now.

Unless someone has a flash of insight I guess I'll just add an event that removes the items and hope that will be the end of it
