I fixed it enabled legacy mode then disabled it worked after that somehow or another it didn't overwrite anything I installed since it was rather accidental
Not sure if it's this mod or not but the only 2 lightsaber related mods I have are this and jc's darksaber darksaber crashes the game on equip im sure its a simple fix but i dont remember jack from when i was messing about with modding this game a long time ago. Equips shouldn't overlap that uses slot 255 this doesn't touch that slot from what i've seen. Fixed it by enabling and disabling legacy mode not sure what I overwrote but it seemed to work.
