For example: Fir Wood Sawmill help text says: "On this search your explorer will find resources which you will need to recruit high quality military units"
Fir Wood Forester help text says: "On this search your explorer will find resources which you will need to expand vour city"
Fir Wood Cutter: "On this search your explorer will find rare, high quality resources"
Mason and Residence also have the problem.

I am guessing some pointers into you text resources aren't pointing correctly.
