I know he is supposedly afraid of bugs and hates people with hats. I didn't know if he was serious though. So I took my hat off, sent Veronica back to the 38 (maybe rex doesn't like her hat?) and went out to search for some NON bug enemies. Rex just runs away once I am in battle. He is set to follow close and attack on sight. What gives?!

Did you put him to use a ranged weapon? That might be it.

Thanks for the reply. I definitely checked that. Even swapped him to ranged and then back to Melee just to make sure.

Just a friendly good morning bump for this annoying little problem.

Has anyone else ran into this problem? I even loaded up an old save and re-obtained Rex just to see if he is indeed bugged in my current save. Rex is acting the same way. He just runs away and hides when I engage any enemy. Oh well, I guess I just want to know if anyone else has had the same issue? Would hate to think that a companion in the game is completely broken for me.
