Rationalism finisher is re-usable

Explorer.exe is messed up so i cant find the patch version

Once you max out the rationalism tree you can keep switching between it and the piety tree and you will receive the 2 free tech bonus every time you go back to rationalism. Will try to test to see if it will work again, don't have the time now so if anyone else wants to check it out. This may be intentional or not, but it seems game-breaking with high enough culture per turn.

Have you got a save you could attach?

Confirmed.

I've also encountered this switching between piety and rationalism. Apart from waiting for the one turn of anarchy... you can basically just keep going back and forth and getting 2 free techs each time.

Save game attached.

After finishing Rationalism, if you switch to piety and switch back it triggers 2 free techs again.

That's, um... a pretty game-breaking bug if true. That should be fixed immediately.
