I have some mods that may have caused my pipboy to disappear. What i mean by this is that i disabled the readius to install the 2500, and now my piboy is gone. I tried to uninstall the 2500 but i don't know what the "In Game Toll" is. can anybody help me?

Don't worry. http://www.adweek.com/socialtimes/wp-content/uploads/sites/2/2015/06/Fallout-4-Pip-Boy.png

In all seriousness. http://www.nexusmods.com/fallout3/mods/12144/? page says that this is a common thing.

Hopefully this helps!

Thank you.
