Broken Boone after Patch 1.06 on PC:

I began a new game on PC after finding that Boone was not completely fixed on the PS3. I turned off the bugfix mod that fixes him and started a new vanilla game.

I got to Novac and started Boone's quest. Before he became a Follower, he was headtracking. I moved around him in the Dino mouth and he would turn his head to where I was. I did his first quest. After he became a Follower, no more headtracking. He just stares ahead like a zombie.

I hope this info helps to fix him in the next patch. The bugfix mod I'm using on PC does still fix him after Patch 1.06 but only on PC so he's not headtracking on PS3. I'd really like to play my PS3 version because it has the Classic Pack addon that I got for pre-ordering.

This is the mod that fixes Boone's headtracking on PC for anyone else who would like to use it.

Earlier post right after new Patch:

Broken Boone after Patch 1.06 on PS3

I loaded an old save and will test later on a new game when there is time. My character is idolized by NCR, vilified by the Legion, Merciful Thug to Powder Gangers and idolized and liked by other factions.

The two issues with Broken Boone were the constant reholstering of his weapon even in combat and the no head-tracking issue. The devs work so hard to make the NPCs like real people, even to having them blink and breathe. With every other companion, you can enter the space close to them and within 6 seconds they will look at you. Not Boone. He's still a zombie and just stares straight ahead, no reaction at all. He's no longer a "companion" - he's a robot...but even ED-E will look at you. So I'm very disappointed if this isn't fixed in a new game I'll test and will probably not play my PS3 version with the wonderful Canteen that I pre-ordered for the release. It just bothers me too much.

The holstering and reholstering seems to be fixed in a 5 minute test in Fiend territory. I'll test that some more too in a new game. Thank you for that but I'm sorry to say that Boone is still broken. When the game was first released, he used to "watch" children as they ran around him and respond to other NPCs and now, ever since Patch 1.02, his reactions to the world, except for combat are nothing, just nothing.

That's not a glitch, Boone just doesn't give a [censored].

Boone still doesn't act right after this patch, but at least he doesn't constantly holster his weapon in a fight now. Whenever an enemy has spotted us but isn't attacking, he takes out his gun, runs circles around me, pointing his gun in my face, grunting and saying "you're mine" over and over.
