Sounds like you have the "Brain in a jar" mod. This mod has to be desabled for you to get the Cogitator brains when harvesting.

As Turbo said likely you using brain in a jar mod.

yep thats the case, i found a workaround as rouge traders sell cogitator brains

I’m not using the brain in a jar mod and I’m having this problem anyway.

Could it possibly be load order conflict?

Maybe.

Try putting my mods at the end of the load order. With My Core od followed by any of my addons mods or oggliss's mods if you have any.

I found the conflict, It was the Legiones Astartes: Primarch Mod by Archaon, After Disabling it everything works fine

OK, I am running into this same issue, and I went into my mod list, disabling mods one by one until the second "Brain" went away.

I didn't have either "Brain in a Jar" or "Legion Astartes", but it twigged me from the beginning that it was a 40K mod due to the fact the both in the stockpile info had nearly identical descriptions.

When I found out what the offending mod was I got hit with a quandry. It is the "Adeptus Mechanicus" series, which requires that it comes after all of your mods in the load order, so I must either remove them or I cannot use any of your mod items that involve Brains. (As their Brains aren't working).

I don't know if the two of you collob or not.... Can the two of you come up with a fix, or do you know why else I would be runniing into this?
