Hi Waragh,

this is a bug with prerequisites and exclusions in the game XML (Basically, to build it you MUST have the prerequisite building built. But at the same time it MUST NOT be built).

I've deployed a fix in my Bugfix mod (among quite a few other fixes). Feel free to try it out if you don't want to wait for the next patch.

Cheers

I believe I said it before on the steam discussion, but I'll say it again here:

I'm just naturally greedy. The more time you have available to spend on things other than hunting down pesky XML bugs, the better the game I get

2 notes for you though, Kael:

1) I've added an update log on the root folder on one of my later releases (creatively named update.log), where I list changes by date (so if you later get a newer version you can just pick up where you left off, and don't have to check the big index against a "fixed"-List).
2) For the latest fixes I've linked the ticket number (I'll keep that up), but I didn't do that for the previous ones. All tickets I have submitted so far are about bugs contained in this mod (or already fixed in 5.2), so if you work down the list in the mod, you might just drop the whole list of tickets without wasting time on them.

You can either detect them by the user-account that created the ticket (if you can see that), or that their subjects all have the same (or very similar) structure:

[Bug][XML]{Category}: {Name of Subject(s)} - {minimalistic synopsis}

Example:

[Bug][XML]Improvement: LaborMission & LaborOracle - Invalid Exclusions

Cheers, and have a great weekend!
