Hi!
Q: How long does each season last in the current build? The wiki seems to be outdated.
A: Variable. Spring = 15 days, Summer = 18 days, Fall = 14 days, Winter = 10.
Q: When winter comes, do you lose the seeds for any planted crops?
A: You do.
Q: How are wild crops assigned? Is it a certain # for the whole map, each z-level, or does ever exposed dirt block have a chance to spawn them?
A: Do you mean, how I generate the plants on the surface? It's just random noise.
Q: Deconstruction has its own skill, are any associated with construction?
A: Wood work, stone work, metal work, and void work are.
Q: What level farmer do I need to get new seeds at least 20% of the time?
A: There are two perks for the farmer which increase plant quality. Quality affects the growth time. Each plant has individual drop %'s and humans have a slight racial buff to this. Harvest drop rates are around 90% to drop 1, 5% to drop an additional 1. I'll be making a change soon for quality to factor into this.
