I can't equip some armors like the Deathstroke armor, Arkham Knight armor, and Radec's armor too.. need help, i tried closing and opening the game and restarting my computer too but i doesn't work, i don't want to delete my save, it's level 56 and is my favourite character. but if there's no choice, i'll go delete it.

Can you be more specific? Assuming you installed the mod correctly, does the armors present in game? Do they make your player invisible when you equip it? If you can't just equip it like what you said, the only thing I can think of is you are equipping an armor/armor part that is flagged quest item/persistent and is biped the same as the said armors that your are trying to wear. The game won't allow it. What you can do is unequip the armor/armor part that is flagged quest item/persistent. Hope that fixes your problem. Goodluck!

@"broccolimonster" Well, that worked.
Thanks!

Glad it did. Enjoy gaming! Cheers!
