How to remove free promotion from tech?

[Ryika]

So, once again I've been playing around with Modding, adding things and changing objects. All the fun stuff. Now I actually want to remove the Miasma-Immunity for workers-Promotion (PROMOTION_MIASMA_IMMUNE_WORKERS) from the Alien Biology tech. Obviously, this is probably a very easy thing to do, but with my very limited understanding of the subject, I can't get it to work. Which is a shame. And google, which was a great help with issues I had in the past, doesn't really help me solve the issue either... so... I need help. How do I remove the free promo from Alien Biology?

Using SQL:

DELETE FROM Technology_FreePromotions
    WHERE PromotionType = 'PROMOTION_MIASMA_IMMUNE_WORKERS';

Alternatively, using XML:

<GameData>
    <Technology_FreePromotions>
        <Delete PromotionType="PROMOTION_MIASMA_IMMUNE_WORKERS" />
    </Technology_FreePromotions>
</GameData>

Thanks... but... that would delete the promotion completely, wouldn't it? I actually want to keep (and re-use) it, I just don't want it to show up in the alien biology tech.

No, it just removes the entry in the Technology_FreePromotions table, not the entry in the Promotions table.

Alright, got it to work! (In what is probably the most inefficient way possible) Thanks a lot.
