Aargh, I didn't have the recipe in NEI and trying as described in the questbook didn't yield anything, I tried making a pestle and mortar too and that didn't help. I came here, saw this, restarted and now the modpack's not even listed in the launcher! Not having much luck so far
Edit: I restarted the launcher again, the modpack appeared, and playing it, the recipe for seeds appeared. But now the hostile mobs have disappeared! There were loads in my world before, and I'm still playing on Normal. Any ideas as to possible causes? Going to restart launcher again, since I no longer need the seeds recipe it doesn't matter to me if it disappears again.
