I was poking through the tfc-server.toml config in defaultconfigs, and I think I found an error. In the [blocks.crops] section on lines 496 and 500, the explanation for what cropGrowthModifier and cropExpiryModifier are is the same. The first sentence separates the two, but the second is the same.
"The modifier multiplies the ticks it takes to grow, so larger values cause longer growth times. For example, a value of 2 doubles the growth time."
Just wanted to point it out if that was something to be fixed.
