The extended snow area should not have any major terrain changes, but there is a possibility of new rocks and trees that have the potential to destroy parts of bases, or spawn on top of tames and destroy them. It is in your best interest to remove valuables from these areas and relocate back in if you desire after the biome change takes place. Anything within the changing biome areas has the potential to be deleted and lost.
what does do u mean by potential to be deleted and lost. Is there any way i can know for sure if my base gonna get rekt or not ?
