Elf Problem

If you don't have the CPELF_Shard_Harvesting_Amarian in your tech tree, you won't be able to build on them.

If you do have that, post your files and I'll have a look.

That is in my tech tree.

Thanks for looking!!

There's no problem with the tech tree.

My guess is, you're using a custom faction with a RaceClassification tag that is not CPELF. This will disable all the resource buildings, not just the shards.

Shards are the only thing (at least that I've found so far) that I can't build on?!?!?!

Well with that raceconfig and the files above, I can build shrines on shards.

Make sure that you don't have copies of files in subfolders or such things, as that may be interfering with your mods.

HF, should be bold line above be as shown or should it be "<RaceClassification>Elves</RaceClassification>"?

If the RaceClassification is "elves" then I can build on anything but Shards.  If RaceClassification is CPELF then I can build on shards but I have double improvements as shown below:

The double improvements are from this line

<SelAbilityBonusOption>CPELF_raceconfigabilitybonus</SelAbilityBonusOption>

it is explained here: https://forums.elementalgame.com/397668

If you remove the line, you will remove all "kingdom" versions of the buildings, and have only elven versions left

I assume you mean the one in my Faction_Loraaan.xml?

Yes. The line isn't in the latest elf version.
