Korhal's Aftermath

• Fixed issue in which "Korhal Building Debris" was disallowing use of the furthest south vespene geyer in the bottom-right natural.
• Replaced "Bridge - Mara Sara -" in the bottom-right natural's secondary entrance with "HotS - Korhal Bridge".
• Moved the gap fillers around the bridge in the bottom-right natural's secondary entrance, and hence increased the amount of manmade cliffs.
• Moved back cliffs to the north, so as to increase the amount of tar.
• Added slightly more "Zerged" doodads to the south.
• General tweaks to the terrain textures.
• General tweaks, additions or removals of doodads.

Still some positional imbalances - the outskirts of the map have lots of elevated terrain to the north, west, and south, and I have not made said terrain unpathable - units can hide here, whilst they cannot hide in the south-east and east sides of the map.
