The Advanced Aurorus Arboretum says it gives +30% tourism, but the planetary income tooltip only shows tourism as +15%. Looks like the increased tourism from the upgrade didn't get applied. It's also difficult to track down the effects of tourism, you have to go to each core world and examine the planetary income tooltip for each one.

How does +11% -50% -10% add up to +0.5%?

Baratak Grove's Spore ability does not seem to give any production input points points to the planets in the Baratak home system.  They both got resource deposits, but no industry, technology, wealth, farming or influence displayed.

Edit: Once colonized, the planets do indeed have production inputs to provide.

Known bug. They show as 0/0/0/0/0 until you colonize the planet. So you don't know what you're going to get until you colonize, but that will be fixed.

Factions op

Not only known but mentioned in the .70 change log.

In my current game I am unable to assign a leader to the Endless Emporium. Hovering over the header of that column shows a tooltip that says that a Minister of Finance is required. There may be similar requirements for the other 3, but since I'm already able to place leaders there the tooltip isn't showing me requirements anymore.

Edit: I just started a new game as the Yor, and while the Endless Emporium is locked at the start of the game, the other 3 are available to me right from turn 1.

What race are you playing?

I'd recommend you do a verify files to make sure you don't have any installation problems. The columns should at least be labeled.

My Factions don't have labels either, but it does say "coming soon" when you mouse over "Factions".  Playing as Terrans.

I started a new game as Drath and now I too have only "Name" for each of the 4 factions. My previous games on .70 were as Baratak Grove and Corporate Sector, and they were able to assign leaders to factions, but I didn't check for that on the very first move. So maybe something is unlocking them?

What race are you playing?

Ok, it appears that any race I had made customizations to in a previous alpha version won't have the Factions window available if I start a new game and keep the old customizations. I erased all my old race customizations files from my My Games\GalCiv4\Factions\CustomTemp folder, started a new game as Drath, and now the Factions window is available.
