I'm having an odd issue with version 1.2.4 (so I can play on the currently stable vintage story build):
It doesn't seem to be adjusting for month length, and I'm not sure where to go to manually tweak things. I'm playing on 9-day months, I planted flax the first day, and about 6 days into the month it says it will take '8 days to reach the next growth stage'--and it's still on stage *1*.
Vegetable crops seem to be adjusting properly? (Onions and carrots are already at stage 2 after a few days).
I'm not sure what's causing this.
