Problem: Confucian School's +5 Science yield per adjacent mountain does not occur when next to the Venicunca natural wonder.
Steps to reproduce: 1: Place anything that benefits from mountain adjacency near the Venicunca natural wonder. 2: Experience disappointment.
Expected behavior: Venicunca natural wonder should trigger mountain adjacency bonuses, since its description says it's a mountain range and the tiles in it are clearly supposed to be mountains.

Most probably the devs simply forgot to set the "IsMountain" tag on all Vinicunca tiles.
