Do the Religious Shrines work?

[Rusty_Nail]

I have noticed a couple of times when queueing the Time Shrine that I get the message that I "already have a sytem wide facility of this capability", which is news to me. A Time Shrine III should add 15% to mineral production. Maybe it adds nothing if you already have a System Mineral Scanner III(adds 30% max to same). But I don't HAVE a system mineral scanner! Could it be something else? Or be a bug? For example, I DO have a System Radioactive Collider III (adds 30% to radioactives production). Could it be that you can only have one such system resource amplifier in a system? If so, the Time Shrine is rather useless. And it would be nice if that were stated somewhere.
