Frankly, I think you're going to find a lot of your answers in the gameplay setup itself. Chaotix created this as a divided town modeled on Rubicon. Rubicon's divided town never really took off because I did not provide sufficient incentives for the factions to fight. There were also two pure pro-town roles that ended up being far more powerful than I anticipated. Chaotix knows this and has almost certainly adjusted the mechanics to ensure that some fighting between the factions will occur. I think it is very likely that some townie factionalists have various goals and/or abilities that are designed to cause a bit of chaos. Some of that is likely at work here.
