I was shocked today when I was travelling from an existing SW world to a generating ROG world.
I set 'start from Autumn'. However when i arrived at ROG, it was summer, and told me 0 day left.
I was totally shocked.
Luckily, the ambient temperature was normal (around 40 deg), and no wildfire appeared.
1. Start from a SW world. 2. travel to a ROG world and set 'start from Autumn'.
