Hello! I really enjoyed your architect's mod, but I'm struggling with the Cenozoic one. I've reached the part where the Eotetraodon is introduced, the question message asks me to create a tank with them. However they aren't available to purchase or research at my rank or the next one. I've checked the message log and there isn't a trade or sale available of the fish either. I'd love to keep playing, and I'm hoping this is an error on my end that you could help me resolve? Thanks!
