If you angle your camera over it’s left shoulder it’ll damage enemy’s, it’s your camera angle you need to turn to do damage (it’s bugged out) so this is at the best a work around to still cause damage
I created another bug report about rhinos if i can send together to the same person ! it has to do with attack tamber so now instead of being the mount and with yours when you use spear she keeps locking and changing the attack button disabling all the time is very annoying. the strange thing is that when it launched it didn’t have these problems was something that was tweaked and tested.
