I haven't touched the new zip... (I assumed it was the same as the previous due to the matching size) So, I can't help with the first question (there is a limit to the number of ants that can be on the field, and each ant takes a different number of slots). I envision confusion regarding the egg limit and the number of ants on the field, but hey, I could be wrong. Anyways, moving the queen wasn't a thing before, so I doubt they'd add that without announcement. (It is apparently planned, though, so stay tuned, I guess.)
