Howdy there,

If a volcano is raised either by an event or spell, it will not update the tiles in the Strategic Map view.

#1) Start/load game
#2) Play until a volcano is created. (Or create one via spells)
#3) Press key assisgned to Strategic Map View

Results 2/2:

A) The tile where the volcano has appeared will remain as it's previous terrain. (Mouse over tooltip is properly updated though (over the minimap))
