text from mod in tooltips question...

[pompachomp]

hello. I was wondering what mod is doing this, in the tooltip of a piece of gear it says "Source: (place)" . .(place) being a variable which shows where the piece of gear comes from. Afaik, i dont have libperiodictable3.1 at all or mendeleev...so I'm not sure what's doing that feature . Hope someone knows.
