So I was sick and tired of town gov being a useless fucking crier, because let's face it, Crier is very weak in current meta.

Unfortunately, excluding crier from town gov tends to cause a save failure rate of 4-7%.
And any weight below 0.3 for crier tends to cause a very small save failure rate that is <1% for 0.2, but increases to the 4-6% range as you reduce weight further.

What are the technicalities behind this? What causes that save failure rate and what is a possible scenario where the save "fails" because there's no crier?

I mean, to take a 7% chance max for save fail to make the town stronger seems like a good trade-off, I'm just curious for how does the save failure rate work, especially in the scenario where everything is fine EXCEPT crier weight being dangerously close to or effectively zero.
