Beta 5 Cannot colonize barren world even though extreme colonization has been researched

I had the same problem and I am wondering if it will fix itself when I research atmospheric cleansing or the actual barren planet tech? Definitely a bug.  

Was actually just about to post this very same issue. I wonder if it is in any way related to the Adaptable trait that seems to allow only Barren world colonization (haven't experienced this myself, but it has been reported on this thread).

I've seen that thread, but my custom race doesn't have the Adaptable trait.  So I think it's a separate issue, but I could be wrong.

Anyway, I went ahead and researched the Barren planet tech and I still can't colonize the planet.  Atmospheric Cleansing isn't available until the Age of Ascension, so it's going to be a good long time before I try to see if getting that allows colonization.

I just read on steam forums that researching the tech allows you to colonize all except barren worlds like the INVERSE of the racial pick.

Something is very broken!

Oi! Oi! I hope it's an easy fix.

I am able to colonize BARREN worlds by picking 'colonizing level 1 extreme worlds' as custom racial trait. 

Probably it is reserved for traits?

I am definitely now seeing this issue with a new race.   Research extreme and get frozen, aquatic, etc. but not barren.  Definitely weird.

It's not working as documented by the tooltip, so it's a bug no matter whether the tooltip or the implementation is bad.

What it looks to me is in the tech tree Barren is not researched even though you think it is.

Yes, I have researched the right tech, Extreme Colonization and also Barren Worlds but instead of getting access to Barren worlds I am now able to colonize Frozen worlds without having researched that added tech for full functionality.

Also running into this issue. Have Extreme Colonization researched along with every mastery spec and it won't let me colonize a barren world.

ok im looking at the planettraits xml and comparing frozen and barren worlds

this is what appears to be the difference to me 

barren 

<ColonizationPrerequ>
<Stat>
<Option>CanColonizeExtremeWorld</Option>
</Stat>
</ColonizationPrerequ>

frozen 

<ColonizationPrerequ>
<Techs>
<Option>ExtremeWorldColonization</Option>
<Option>PropagationTech</Option>
</Techs>
</ColonizationPrerequ>

so if im reading this right there are no techs that allow barren worlds to be colonized

probobly changing barren worlds to  

<ColonizationPrerequ>
<Stat>
<Option>CanColonizeExtremeWorld</Option>
</Stat>
<Techs>
<Option>ExtremeWorldColonization</Option>
<Option>PropagationTech</Option>
</Techs>
</ColonizationPrerequ>

should fix it

although im not sure what the propagation tech is off hand.

or if the game will treat that as you need both or you need eithar

so looking a little more propagation tech is the first tech of the yor population tech tree so im guessing that having that line in there was a cheap way of giving them the ability to colonize barren, aquatic and frozen planets without having super abilities working yet

as a side that means anyone using the yor tech tree can colonize frozen and aquatic worlds right off the start regardless of having adaptable or not

ive made the changes i suggested and am testing it now although i had to leave propagation tech in as a possible requirement for the three planet types since i think the yor tech tree doesnt actually have an extreme planet colonization tech ability

after testing the changes i suggested the result was that you now need both the tech extreme world colonization (or propagation) And the ability adaptable

so having multiple tags as a requirement right now means that it requires all tags to be complete

the next questions would adding 

<ColonizationPrerequ>
<Stat>
<Option>CanColonizeExtremeWorld</Option>
</Stat>
</ColonizationPrerequ>
<ColonizationPrerequ>
<Techs>
<Option>ExtremeWorldColonization</Option>
<Option>PropagationTech</Option>
</Techs>
</ColonizationPrerequ>

in the same file cause the file to crash?, allow it to finish when one or the other was met? or only allow it if the first or last condition was met

anyway im off to bed need to be up in the morning i can continue testing a fix tomorrow evening 

*edit this caused an error dialog /edit*

i think i stumbled over the solution while taking a shower. Anyway change the planettrait.xml to have just the stat tag and then change extreme world colonization tech to give the stat. This would be annoying though since every race tech tree would need to be modified. Another option would be to change the ability to provide the tech but im not sure how that would work for counting techs toward tech ages  

Any more info on puzzling this out?

Im just on my way home now

so after a bunch of testing i cannot get this to work properly

i can get the planets to be colonizable eithar one way or the other if you have the tech or have the ability but this requires 2 different setups 

or i can set it up so that you can only colonize if you have both the tech and the ability

maybe someone with better skills then I have can fix it

some thoughts 

having the ability grant the techs should work but i cant figure out how to grant techs (and i dont know how this would effect tech progression)

having the tech grant the ability would work but i cant figure out how ( this would be annoying as you would have to edit all tech trees)

having each of the tags under <ColonizationPrerequ> be treated as an OR operation rather then an AND operation would work (similar to how the <option> tags work but putting them outside the <tech> and <stat> tags causes an error

Good catch.  I had the same problem in my gameplay example.

Observations from testing:

-Most races can't colonize Barren worlds with any level of technology.

-Races with "Adaptable" and any tech tech tree other than Yor can only colonize Barren worlds until they research Extreme Colonization.

-Races with "Adaptable" and the Yor tech tree (including the Yor) can colonize all three.

-Races with the Yor tech tree but not "Adaptable" can colonize as though they have Extreme Worlds technology!  They are able to colonize Frozen and Aquatic without choosing adaptable but they cannot colonize Barren worlds.  They get most of the benefits of Adaptable but get 2 other abilities to go along with it.
