Great Prophet not founding new science

[Neomega]

I had two "great prophets". I used the first one to discover "Theology".

The next one said if I use him, it will give me "Civil Service".

So I used him to "discover new technology"
It went through the little graphic display and such.

The tech tree still indicated I had not yet researched "civil service".

I went back a few games, (because I didn't notice for a couple of turns the prophet discovered nothing), and retried it, and it still failed.

That's not a bug.
Later in the game Great People do not instantly discover techs but just contribute a large amount of beakers towards the techs research. By using this Prophet for Civil Service, research was probably done for 75%.

It's fairly clearly marked - the tooltip over the lightbulb icon says "xxx beakers for research of <tech>" - though it does say "Discover <tech>" at the top, which is a bit misleading.
