I'm playing the current patch (1.042) on Normal difficulty with Rogue Hawk, Starlancer Lise and Godhand Kevin, just finished fighting Lightgazer as my second God-beast and something weird's going on. I've been using Hawk as a caster lately so I decided to stick the caster-boosting gear on him to up his damage. For Hawk's weapon that's the Bishamon. So I messed around in the Temple of Light some, beat Lightgazer, then came out and decided I felt like mining more crits instead so I went to switch to the Elf Dagger. But the game wouldn't let me. Every time I clicked on Elf Dagger in the menu, the game would make the cancel noise and not change his equipment. It still displayed a stat change as if it could switch (unlike trying to equip a spear or something, which doesn't), it just wouldn't let me change it. I messed around with some saves and followed it back to the Temple of Light, when I first put it on. From that point, I was still wearing the Elf Dagger. I could switch with any other weapon freely, which I tested. But as soon as I equipped the Bishamon I once again lost the ability to equip any other weapon on Hawk. I could change any other piece of equipment of his, and it had no effect on anybody else's ability to equip things. Testing it on the other characters, the same thing hasn't happened with Kevin's Ghost Hand nor Lise's Wolf Fang. It's only Kevin's Bishamon that locks him out from equipping any other knife. I might just mess around with a cheat code to switch it out if I have to, but I wanted to let you know too because that's a pretty specific glitch.
