I don't know if this kind of bugs should be reported here. I noticed a problem with Nuzleaf and the move Razor Leaf. First, the Nuzleaf I got in Sheridan Village didn't know Razor Leaf, whereas he should have known it. Then, I bred this Nuzleaf to get a Seedot and to evolve it and again, it didn't learn Razor Leaf. I tried it twice: It evolved once at level 14 and once at level 23 and in both cases couldn't learn Razor Leaf.
After searching the whole Rejuvenation forum, I'm pretty sure the issue hasn't been reported yet. But I'm wondering if it's really a bug or if the problem is only appearing on my own save.
