I decided to make a research-planet, finding a 19 planet with a precursor artifact tile (+300% research, it says). Now, I have on that planet the initial colony (+10 research), 4 xenolabs (+9 research each) and 2 research centers (+12 research each). So that's 10+36+24=7+ research. And that's what it says in the summary of the planets various productions.
But one of the xenolabs is on the +300%-tile, where did that bonus go? Is it hidden?
Hmm, looking at a planet with a +100% food tile with a farm on, it does produce 20 mt \ week. Yet the summary says 15 mt \ week. It could be an idea to have the summary state count in the tile-bonuses. Or did I take a wrong turn somewhere and misunderstand the whole thing?
