How does it work, random planets get random amount of arable land (based on planet quality)? I'm currently editing Six Pillars to bring it up to date (missing resources). If I add arable land to planets manually, will it get another arable land on this patch? Or since I'm editing this map on v3.0 patch, it wouldn't have any arable land unless I add it manually?

Btw it's a shame that Map Pack DLC lost it's value once Crusade was released and you didn't updated it to reflect changes in needs for particular resources/trade goods.

EDIT #2: Also how can I add more than one arable land tile to a planet in map editor?

If the game doesn't find any arable tiles in the galaxy, it places the just like you were starting new map. 

I believe the map editor only allows  the placement of one improvement (arable tile or otherwise).  I'll take a look.

Updates 4/24

Base Game

• Typo fixes
• Various crash and stability fixes
• Fixed crash caused by having a unit in transit to a planet, and then the planet is destroyed via event
• Fixed crash in civ builder if you try to create a civ before starting a skirmish
• fixed issue where the "cannot build close to starbase" error message was showing %d instead of the actual distance when loading a save game
• Fixed issue where exporting a ship design from the title screen would export a cube instead of the actual model
• Fixed text coloring issue on the "Traits & Abilities" tab button on the civ builder

Crusade

Ships with citizens on them can no longer be scavenged (prevents a stuck turn)

Intrigue

• Added the ability to disable Crises to game options
• Fixed issue where switching from a government with fewer cabinet member slots, to a government with more cabinet slots, would cause there to be an entry filled with a cabinet member to be grayed out

I don't see the issue with the Extravaganza removing the Port of Call from the build list.   has this been fixed?

Here is an unmodded save with Crusade 3.0, I just booted the game, removed all mods from mod folder, to get this, Terran freighter 91 range and has already passed 100 tiles to thier nearest planet. Its quite easy to replicate, just boot the game play on a large map with 4-6 AI, sit back and wait for them to reach you (i use fow cheat to actually watch them).

Possible bug... I had a war start by a treasure hunt ship being attacked no formal war declaration popup.  Might have been collision error?  

I also have had that happen.  Even worse, before turn 10 I had the starting and armed survey ship of another race attack and destroy my first colony ship while it was going to a planet.  This has never happened so early in the game before 3.01.  My first thought for both of these was that there was a collision error introduced in 3.01.

I don't know specifically about the treasure hunt ship, but the AI was changed in 3.0 to attack colony ships.  

I probably should have mentioned a few more details.  I don't know if it is a bug but there are are reasons to believe it was.  All war declarations should really start with a popup in my opinion (perhaps they are supposed to?) this did not.

My treasure hunt automated ship was near to a terran alliance planet they had just wiped out the Slyne and had 200-300 ships swarming over the huge map playing Godlike at average 20-30 movement.  I had very good relations with them +7/10 and still rising.  So in theory it could have been them continuing their galactic conquest but I'd have expected a popup first not just a very random battle then war.  The surrounding circumstances definitely made it feel like it was a bug.  Should an AI on that good terms even declare war?  A very human thing to do.  Possibly their ships were trying to enter their planets orbit and my ship was in the way.   

I don't know if this is an old or a new bug, and steam won't update to 3.1 yet, so I'm stuck in 3.0 for the moment. I found a lvl 25 planet, which I can't recall finding one pristine before so this may be an older bug or it may be intentional. Essentially, the first two terraforming techs are useless on it as there's no plots available to terraform.  If intentional fine, but it came as a surprise to me that a planet would have zero tiles still to be changed.

I'm also curious, why is it that my first interaction with new species is sometimes an accusation that I killed their ambassador. Shouldn't I actually have met them before they accuse me?

And lastly, why is the number of planets governments can manage so low? Maybe on a tiny map or even a medium map they make sense. On ludicrous however...
