The Muisca have been updated!
So, figures the looping issue actually had different origins than the old one. But the issue should be fixed now (I hope)... The symbol and color were also changed. The colors were changed because they were too similar to JFD's Stalin. And the symbol, although I also liked to other one Zipa did, is done to better represent current symbols of Chibcha-Muisca societies, and also the Sugamoso flag's fancy symbol.
An important part of this update is that the Faith from unused Gold now shows on the Top Panel! So now it's far easier to get a feeling on how much faith you're actually getting
Both Decisions are centered in the political aspect of the Muisca Confederation. One is forming the Confederation itself, for which you need 3 cities. With a huge cost, each city receives a specific bonus (the first more Gold output, the second more Unit production and the third more Faith) to represent the nature of the Confederation. It can only be done before Renaissance, and only once.
The second decision is a reference to the Code of Nemequene. It allows you to get a Free Social Policy and some gold, at the cost of Faith, Magistrates and Unhappiness (the Unhappiness is the biggest blow here). Funnily, it can only be done during the Medieval era, but as many times as you wish. But the Unhappiness is eternal, so one has to be very careful with this one.
