Big Spruce Trees don't generate in Groves

The changelog states:

"Grove

• Snowy terrain with big spruce trees and powder snow traps. Might want to wear leather boots!
• Tends to generate on high-altitude terrain beneath mountain peaks or on hilltops.
• Spawns wolfs, rabbits, and foxes."

Yet no groves I visit have trees whatsoever, no matter the world.

Expected Result

Spruce trees would generate like the changelog stated.
