Exodus Alters Underlying Terrain...?

This may be unrelated, but I recall that at some distant point in the past the devs made significant changes to the land of Illyriad (IIRC, it was the same time they introduced biomes).  Of course, squares with cities were not changed so as not to disrupt player cities.  Perhaps they coded it so that when the cities are removed (for whatever reason) the land changes they meant to implement were implemented?

Here's a bit of an interesting update: I did an exodus off of a terraformed square (don't ask) and it actually converted the square into the proper terrain (as in, instead of normal plains with 3 stone 7 food, it became an actual Fertile Pasture, sheep and all).  I wonder if it was just random, or if that would always happen when moving off of terraformed terrain...

I reported something similar as a bug on 24/01/12. I moved a city from a fertile pasture and it became plains. At the time we had just had an update and I thought it might have been related to that.

Yep, my two were out in The Wastes (egh) and I think the other one I heard mentioned was out East somewhere.

One thing that may occur is that every so often the game converts squares suitable to be "inhabited" by new player cities.  These squares are small woods (elves), plains (humans), small mountains (dwarves) and small hills (orcs) with the relevant resource plots.  It's possible that the squares were converted for re-use, especially if they were in the newb ring.
