Hi, so I've given Veronica the t51-b? power armor to wear, which she does, then gone into v.a.t.s. to see the damage it can absorb with a particular weapon and it's exactly the same as if she was just wearing her default clothing, the robes or whatever. Am I missing something really obvious, is there a quest that needs to be done too make full use of the power armor? Because otherwise it seems to negate the point of equipping her with it in the first place. Thanks for any help.

Related to Veronica and armour, has anyone found that she doesn't seem to progress in her "insights" when she has any armour on.

After putting Veronica in power armor, she stopped following me, regardless of anything I do on the companion wheel. Not even fast travel. Must be one major bug.

Veronica has a bug where she stops "leveling" and gets stuck at a certain number of hit points. Maybe this bug has something to do with adding the Power Armor to her as well. There is a Veronica fix mod at Nexus that is super simple to use and once it is loaded she jumps way up in hit points if she is all ready beyond the level where she gets stuck which I think is 12.

I am using the Xbox 360 version and I am having the same problem as soon as I gave Veronica power armor she will not follow not matter what do, though she will show up at random from time to time, down side is that I have no idea where she is now so can have her quit and get someone new. Hope they fix it or give us a follower recall button. I did notice that she will follow me when she does appear but as soon as she talks (initiated by her) to me she again stops following.

There's a bug with her leveling and scaling issues. You can get a fix here:

Part of her quest line when she wants to talk is to discuss the BoS and at one point she wants to return there to talk to the big boss.
