I just spent around 20 - 25 minutes flying around the perimeter of the EU Survival map looking for zombies to kill. I saw around 7 - 8 scientists around junk piles. I saw 5 or 6 bears. I saw zero zombies. I am the only one on this server, so they should be out and about. In my previous bug report, I reported that these zombies also are not dropping Frankenstein body parts. It is likely the same on both EU and AU Survival.
