Yeah, I just noticed it, but it seems my character is around 30% taller than everyone else. I have no Idea when it started, or what I may have activated to cause it.

This may be best suited in the mods forum, I will ask to have it moved there.

oh hey, thanks.
Now does anyone have any sort of information on this?

Have you tried opening the console (top left key below esc), clicking your character, typing "setscale 1" (without "s) and hitting return?

If you're running the most recent version of Powered Power Armor, that's the cause. I added in power armor scaling - anything wearing power armor is, I think, 22% taller. You can disable the feature from the config menu if you want (general config I'm pretty sure).

Yup, the Setscale thing did it. No more bumping my head on doors. Thanks.
