Experimental flow field pathfinding
Kind of got flow field generation down to a minor stutter...
Struct test - slower (50%)
Chunked Flow Field with "portal" connections coming soon(TM)
So close to having working flow field that's reasonably fast, except sometimes units get stuck alternating between nodes
Various improvements and optimizations but units still get stuck between portals
Fully functional flow field pathfinding with chunks / HPA*
Removed debug line and set hard map limit of 30k x 30k
The flow field pathfinding is now better and units can correctly approach buildings again. The flow field will update automatically when new buildings are created.
