hurricanes, tsunamis, or landslides might be too complicated (programming-wise) to add, but they are still great ideas and I hope they do manage something like that. As for floods and volcanic eruption, seems doable and the volcano def needs to happen cuz as far as I can tell: build base on volcano = win
p.s. Sry for neglecting the new dossier and getting off-topic but don't think I'm not absolutely stoked about it!
