Issue description

Astar2D get_id_path() and get_point_path() return different results. In my case, get_id_path() returns an empty path, whereas the get_point_path() does return a path.

I am not sure what conditions are triggering this, I tried calling the method right after initialising the Astar2D, by getting a path for a single tile movement, in that situation it worked fine.

Steps to reproduce

After opening the reproduction project, just run the app. After running the project, click on any green tile and press the button on the top right. If the bug reproduces, then an assertion should kick in and point to the code location for the logic. In the output there are also both results printed from the two functions.
