I have checked his companion wheel, he is set to attack when I do.
I have also played with the wheel and his settings quite a bit, but nothing seems to work. I've told him to do both Melee and Ranged, be Aggresive and non, and yet he still runs off whenever I enter combat.
So far, I've discovered that E-de bugs when you upgrade him, Boon Bugs when you dismiss him, and now Rex is bugged.
PLEASE, someone help me.
And Obsidian, as a gamer, I would have happily waited for you to fix your game before you robbed me of my money.
Thanks.
