Where are the silacoids? The last time I saw one (and only one) was several versions ago while attacking an ethereal UFO; never saw one in my latest playthrough but of course waspites, gazers, and sectopods were plentiful. With the Church beastmaster able to tell about the silacoid, you'd think they'd use them too but I never saw them in any Church battles either.
Also, there's mention of a giant cockroach which I've never encountered. Is it just rare or unimplemented?
Finally, I noticed that the cloning center allows soul gems to be revived back into magical girls. Seems pointless as there's nothing to do with a magical girl once she's all researched out (and you can research the same one over and over), but maybe this is just a placeholder and the revival's real function in the future is to give you a magical girl of your own like a new type of hand or an auxiliary. Is that about right?
