faustmouse's building buttons are not showing up at all for the GP to build. All the shrine ones are even the ones you can't build in the city but they are greyed out as expected.
I think TB changed the XML but the Scout could not upgrade to a Guide because of the XML in the Subdue Animals unit infos file had it upgrading to a tracker. All you need do is uncomment that code to see the problem.
From the code it looks like the two tags used should be working.
Faustmouse's buildings are listed in the Can Construct section under Special Abilities in the pedia.
I removed the Guide from the Subdue Animals unit infos file cleared the cache and the Guide is shown as Upgrade in the Pedia.
I don't know what i do wrong
