If you bring Todd to live with the pirates, he will permanently stay in the captain's room while simultaneously standing besides Donnie outside.
If you ask Donnie about Katya you just auto exit out of dialogue.
Now I sincerely hope the following are bugs and not a deliberate design choices:
As a non-spear melee user you can't hit some of the hives at all while standing on land:
H8 - northeast corner Hive
I6 - northeast corner Hive, also cannot be reach by water due to terrain blockage! Can't use TNT because it already spawn shit loads of Locust. WTF!
I7 - southeast corner Hive, especially annoying w/ multiple Heartbreakers patrolling the water.
L6 - Middle of the map/Eastern Hive, not reachable by jet because it's sitting in a self contained pool of water!
