When me and my friend were exploring the ancient archive's, we powered the place up and started exploring , and when we were done we realized there were no Fountains of knowledge in the ancient archive's.
The mods that I used during world generation where:
Server mods: Global positioning, Imperishable thermal stone, show me (origin), and simple health bar DST.
Client mods: Action Queue reborn, Advanced controls, Craft pot, [DST] Nautical HUD, DST Wheres my beefalo, Geo metric placement, gesture wheel, place statues, and snapping tills.
Theories: My guess is either "Unlucky RNG" or a bug involving world gen and the mods.
