Not much help in that link. As mentioned I have four people, and I think I've done pretty much everything within the town walls. There might be some guards in the camp I haven't spoken to, not sure, but pretty much done it all. The only thing I can think of is that I haven't asked to get the two suspects jailed (don't really feel like it at this time). I've been at the north-west gate. The first small group of zombies was no problem, but further away from the town the groups seems to be way larger.
