Details:
This is not a problem with default ruleset but a custom ruleset may have
sequental definitions for warmer_wetter_result (as well the three other
_results). The randomly chosen tile in
void global_warming(int effect) and
void nuclear_winter(int effect) (in maphand.c)
might hit one tile several times during one disaster resulting in unexpected
change of terrain.
For example, with following definitions
[terrain_plains]
warmer_wetter_result = "terrain_swamp"
...
[terrain_swamp]
warmer_wetter_result = "terrain_ocean"
a plains tile might collapse into ocean in just one occurrence of global
warming.
Also, the code seems to have been written assuming that the random tile
picker never hits twice on the same tile since the iteration is stopped after
{total number of tiles on the map} times.
