Bearger never spawns in an autumn-only-server

No matter how many days you skip, Bearger never spawns.

I created another world, whose presets are very long autumn + no winter or spring + very short summer for a comparison purpose. In this world, Bearger comes in the first autumn, in day 40. The spawning mechanism is different from Deerclops, but both of them have some glitches inside, maybe.
