I encountered a world generation issue while playing a match with some friends, which after some testing in single player, I've been able to track down to being caused by a bad interaction between using the "Scattered" world generation setting, and strategic resources being set to "abundant". The issue manifests follows:

• No luxury resources spawn on the main continent.
• No hyperium or mithrite deposits spawn on the main continent.
• Hyperium and mithrite never become available to buy on the market.

The issue goes away if either of these setings is changed.

Out of 4 tests, using the "/lightmeup" and "/knowledgeispower" commands to see the whole map and all of its resources, 2 in the vanilla version of the game, and 2 with the ELCP patch installed (because I initially suspected that the issue might having something to do with that patch), in all cases no luxury resources spawned in any region of the main continent (though they did spawn on the islands where the players started), and in all but one test no hyperium or mythrite spawned on the main continent. In one test three mythrite spawned on the main continent, and no hyperium.

Also of note is that in all 4 tests, every region in on the main continent had exactly 6 strategic resources deposits. My guess is that what's going on here is that there's a cap on how many resources can spawn in each region, and that each type of resource spawns in the same squence every time, so that by the time the later resources try to spawn in, there's no room left for them.

I would guess that in the "Scattered" world generation setting, the sequence is something like this:

1. Spawn luxury resources on the player islands
2. Spawn 1st-tier strategic resources on the main continent
3. Spawn 2nd-tier strategic resources on the main continent
4. Spawn 3rd-tier strategic resources on the main continent
5. Spawn luxury resources on the main continent

Another contributing factor may be that the region size was set to "huge". I didn't check if the issue occurred at other region sizes.

A seperate issue that occurred in the match where we first discovered this issue is that no volcanic terrain spawned anywhere in the world, even though we enabled it. I was unable to test what the cause might be in single player myself because I don't own the Inferno DLC, but here's a copy of the save file for where we are right now in the game:

Longship Match 3 - Turn 106.sav

Also, here are save files for some of the tests that I ran:
