Timber and Stone v1.5 {PX-Flash}

The update for this version is short and sweet: 1.52 fixes pathfinding.
All pathing is now being calculated on a separate thread from regular game logic, and across multiple frames. It is now virtually impossible for your settlers to become lost. In fact, the only situation where a path-find could possibly fail is when attempting to path to areas that are quite literally unpathable, if you wall in your settlers, for example. Another major benefit to this is that settler path-finding will now always have near zero impact on your frame-rate.
