Not sure what is going on if its the game or me, I assume the game because it works fine with every game except this one. When I throw my spear it works 1 or 2 times then its like the button RB on my controller unassigns itself and won't let me use it to throw anymore. I have restarted the game, and everytime it does this I have to save and load if i want my throw button to work again. Any Ideas would be appreciated.
