changes:

replaced the central hill with a destroyed village - improves the aesthetics there slightly

moved the archer towers closer to entrances to the bases

moved the mines into the hill - had the mine for the right side village closer to the central path to reflect on the top left village having a better overlook on the top of the path.

added nav mesh blocking volumes to the 3 impassible villages - holding mouse over those areas should result in impassible terrain now.
