I play on Xbox One. I decided to organize and line up all my spare power armor frames that i have either found/stole/purchased. I counted, 24 so far. Mainly stolen from Brotherhood of Steal. So as I was doing this I found that while outside of the power armor I was no longer able to access the Pip-Boy. I tried hard reset, I tried quicksave/reload, save/reload, loading a previous save. the only thing i have yet to try is uninstalling/re-installing. Any ideas? Do you know if I uninstall/re-install....will I lose saved data?

I think your saves are stored via the cloud if you have it enabled. And if you haven't messed with the settings then it is enabled by default. So your saves will be fine if you reinstall the game. This has happened to me too but a reload always fixed it. :/
