I was playing a rather horrible game where the only thing going for me was that I was charging 0% tax - trade was keeping me in the black. (in the green?)

I noticed that as soon as I cranked my taxes down to 0% though, the population on my single planet went to riot mode. I did ye olde mouseover, and it said Unrest: -0% due to tax, +2% due to population, -0% due to city imporvements, -23645235626% due to native ability.

Well no wonder they're unhappy! They naturally get a billion times crankier! Must be that time of the mon... GAHH my woman just punched me for some reason!

But the strangeness does not end there. I trashed one of my factories and tried to build some Happiness Crystals. The faded-out happiness crystal logo was definately on my map, I clicked on it, and clicked BUY, and went to next turn. When I came back to the planet, it had built a market! I thought I misclicked somewhere, so I tried it again and same thing. I finally got it to work by waiting a turn before buying it.

They didn't fix my problem though, so I built an Entertainment center instead, had to do the wait-a-turn thing. That seemed to work. My approval instantly went to 100%.

*flexes* first bug report! woot
