I am up to date on Patches and am using the BUG Mod. Units will start with whatever upgrade attributes which vary by City. I cannot select the upgrade any longer. As an example, Musketmen will usually start with * and **, I cannot select gunpowder. I have no ability to even see the upgrade options. This just started so I leap to the conclusion I picked up a bug or virus somehow. The question is: is there anyway to fix this short of uninstall/reinstall? Thanks for any assistance.
