Necron campaign bug - Battleplans

Good evening,

Currently playing the Necron campaign. Dotted about the sectors (Agripinaa being one) are worlds with "Imperial Database" on them, indicating that at evolution level 3, you gain an enemy battle plan every 6 turns.

I'm approaching 100 turns, and own 2 such planets, but my battleplans have remained at 0 throughout.

It's by no means a major issue, but I thought I would highlight it.

I got some probably from special missions, but they are totally insufficient to unlock areas.
