I think it's an issue with Rabbit Wand's model and nothing specific to skins.
I just verified the FO skins and their base weapons work, except for the Heart of Rabbit Wand combinations. But the base Rabbit Wand weapon also has this issue. I'll disable patches to test on my own server later today. Not sure how any of the patches could have caused this (especially since nothing should have been changed for the Rabbit Wand class), but wouldn't be the first time I subtly broke something
Also I'll check the rest of the skins just in case.
Oh i see, does it mean it is an original bug from sega?
This game hasn't revealed all its secrets even after 23 years.
I believe there were not so many forces wandering in seabed with rabbit wand , which is a pretty low level item originally.
So it has never been known/reported or even cared about , idk...
