Great pack so far, I like how it's one of the few packs that doesn't end up blowing my cruddy computer's FPS to oblivion. The progression is also quite nice, relying on nature mods and giving plenty of resources to keep players alive and without a lack of resources. Many packs seem to focus on "the hunger challenge" which just feels more limiting than it does challenging, but here farming is a way of gathering resources instead of a food grind. I also like the idea of slowly transforming the wasteland into a place where life can live again.
I have Essence and Reed plants next to the same cross-crops, with no other plants to mess anything up, and it's been over an entire Minecraft week and nothing's popped up there. No Nature Seeds whatsoever. Arrghhh. When I boot the pack up again, I swear I'm going to move my essence seeds into the middle of 4 cross-crops with reeds in the corners because I'm so freaking mad. (And yes, I'm using farmland, not sand, to breed the nature seeds.)
