I have no idea offhand, its quite possible they will it is set as an approval building and is very cheap so I think they should.

Great work as always. The ability to append improvements (so they can be version agnostic) has given me an idea of my own to work on, so if/when I ever get around to releasing it, I'll make sure to credit you.

One thing about this mod, however.  Neither the Drengin nor the Yor can build the Propaganda Center, due to the fact that they get different starting colonization techs.  Thankfully the fix is very simple to make. 

Simply replace this:

<!-- Prerequisites -->

<Prerequ>
<Techs>
<Option>ColonizationTech</Option>
</Techs>
</Prerequ>

with this:

<!-- Prerequisites -->

<Prerequ>
<Techs>
<Option>ColonizationTech</Option>
<Option>ImperialismTech</Option>
<Option>PropagationTech</Option>
</Techs>
</Prerequ>

And, volia! All major factions can use it.  This does mean that this mod might not be entirely version agnostic if/when new factions are released that have an entirely new starting branch for their expansion/colonization (all of the other factions currently have ColonizationTech as a starting branch even if they do call it something else).  But I figure a note in the mod README should be sufficient to handle any future proofing along those lines.  

Glad to be of help!

It's funny (and now I'm side tracking here).  While working on a small home project I found out that not only can one append improvements to the game by putting them in their own xml file, as seen in this mod, I found out that one can append techs as well to a faction's tech tree.  

This might have already been known by the modding community (as I said elsewhere, I've only been keeping the most cursory of eyes on it), but figuring that out for myself opened up all sorts of possibilities.

Turns out though, after a bit of a think on how I want to do this, I might not even need to make custom techs after all.   But having the option to make custom techs appendable is all sorts of great news, IMO.

Version 1.1 is Uploaded

-=ChangeLog=-
Begin V1.1
Changed the <Prerequ>ColonizationTech</Prerequ> to use TechTree instead so Drengin and Yor will use the Propaganda Center.
Credit goes to BuckGodot for catching that one!
End V1.1

Does this work for the 1.2 patch?

For some reason none of the mods I have installed are working even though I have allowed mods and have restarted Galactic Civilizations. Have you or anyone experienced this? I am running the 1.2 patch.

What mods are you using? I have had certain mods stop working but they were shown as culprits when the game starts and you can remove them or fix them. Usually fixing is not hard. You just copy the new xml file from the Steam game files and paste into your mod file. Then you have to reenter the alterations in the mod file.

If you list your mods you will get the specific help you need.

they had the opposite problem in GC2, which never got fixed^^

Annekynn, until it is addressed, I have an 'exploit' you can try. Use the cheat code "createtraderesource' on the grid in question. The resource should replace the building. Then, simply destroy the resource and you have a clear tile. I posted this a few months back, the grids read 0,0 to 9,0, left to right on the bottom row. Next row is 0,1 to 10, 1...and it continues like this until the top row, which is 0,5 to 10,5.  Let me know if it worked. 

Yeah I can release a version without the IsIndestructible, I made them indestructible originally out of concern over what the game would do with the Patriotic setting if the building were removed. But it seems to be a non issue so I can certainly remove it.
