@EduardoPantalones
Do you know if it does it with the 2.5 stable and if not, maybe check the last 2.6 prrelease and see it it happens there ?

I do not, if it happens again I will look at that for you. The workaround was to save, make Zombies Human and reload, and then switch them back to AI after their turn, we are 3 turns past event now. weird scenario :) Thanks for quick response!
Should be fixed with PR 12831 (Fix issue 12822 GameMap#getNeighbors IllegalArgumentException). @EduardoPantalones Please confirm that on the map the issue is no longer experienced. Only hint I have is that it seemed to have been cause for cases where no "capitol" territory was passed on the search for neighbors. Not sure how exactly the setup had been or how to retest it.
