Game Version
3.1 - KKAD

What expansions do you have installed?
All of the above

Do you have mods enabled?
No

Please explain your issue is in as much detail as possible.
Built two statues:
Statue 1 and Statue 2
1. In order to build a heating pipe, you need to build a hypocaust. You can build a hypocaust in statue 1 and the heating pipes will be available for construction in statue 2
2. Gild a statue 2. You will not be able to gild the statue 1, because the game says that it is already gilded.

Steps to reproduce the issue.
Same as above

I noticed something like this playing as the abbasids. There was an option to build pyramid retinue on the house of learning (or whatever it's called). When I released egypt it stopped being an option.

Thanks for the reports!
The one added by @klopkr is a separate bug though as it's only the naming that's actually wrong (but no separate bug report is needed).
