Sometimes this just happens. I kinda love the crazyness, but I know that ppl will ragequit as well. 

There is a double problem with this when they come out and stomp on you. Some times when you do kill the rampaging gods, the trigger for their death is not activated in their controlled lands so you can't send pioneers out to grab the goodies that are sitting in their areas of control. 

When you clear out wildland, remember to take all the lairs/goodiehuts. That will usually trigger the all clear.

joasoze, I've cleared out all enemies and all goodiehuts in ALL wildlands.  They did not clear.  It only happened in one game and not in the others where they did clear.  It is definitely a bug.

I'm pretty sure getting the goodie huts isn't necessary anyway.

I think sometimes the wildland mobs wander aimlessly around the map not fighting anyone and not being killed.  Or possibly they are killed by the AI and it doesn't clear the wildland.

What if the minions could eventually get stronger if they keep get beaten easily so you have to deal with the threat at some point (not linear scaling, something that would give you some time to prepare)?

I started a different thread on my experiences with Delim Skye, and how his horde wandered from one end of my territory to the other before finally attacking a city he had already walked past once.  He committed suicide in a sense, because he never appeared in the battle due to too many creatures in his army ( over 9 apparently ).  I fought him in a different game in his home territory, but he still didn't make it into the battle.   At least I was able to use the mega fire node in the second game, because the zoc vanished after his death ( it never did in the first game).  I like the wildlands concept and have just defeated Abeix without issue, but the Delim Skye portion needs some more work as it is currently broken.
