Why a bug? Village raids have nothing to do with ambushing Aquatoids.
What purpose do the villages serve? Do I understand correctly that:
"Deep Ones Outpost" research unlocks village missions.
"Deep Ones Village Raid" allows to capture communicators.
Researching communicators unlocks USO ambush missions.
Do villages give anything besides the chance to grab the communication device and a few Deep Ones? Is there any reason to raid them once underwater cities become accessible?
Back to my suggestion to suggest bringing explosives to Cyberweb Lair and Zombie Catacombs. The same problem may arise for Ooze Nest, since it uses the same sewer blocks as Cyberweb Lair. I haven't yet run into impassable maps there, though.
Typo in Feral Carcharodon description:
"it's prison" -> "its prison".
After "Shambler Terrorist" is researched, the "Shambler" article isn't displayed.
