Rescoring doesn't seem to work properly

[PaulRotar93]

I've been recently working on a game which was based on using the A* algorithm for pathfinding.
The game is online so the server also needs to calculate the position of each object in the scene, thing which will throttle my CPU up to 100%. So far I noticed that the "cost" property on each hex won't get rescored for some reason, thing which is the main cause why this is happening since I noticed that this is most likely Dijkstra's algorithm instead of A* due to the massive search in all directions.

Is there anything that i'm missing here which is responsible for making the plugin work as expected ?
