Assets

Steps to Reproduce

Open the project (last edited ~2 months ago).
Place a black ramp or tile in any map.
Observe that it automatically changes to white upon placement.
Attempt to use Navigation Arrow Links with pre-existing tiles or ramps.
Note that pre-existing elements no longer interact with the navigation system.
Place a new tile and test Navigation Arrow Links.
Observe that new tiles interact correctly but exhibit the color bug.

Expected Result

Expected Behavior:

Placed elements should retain their intended color.
Existing tiles, ramps, and other elements should work with Navigation Arrow Links without requiring replacement.

Observed Result

After reopening my project after approximately two months, the navigation system and placement of obstacle elements are malfunctioning. Previously, everything worked correctly. Now, I’m encountering the following issues:

Color Conversion Bug:
When placing a black ramp or tile, it automatically converts to white.
This happens consistently with any new ramps, tiles, or stairs placed in the project.
Navigation Arrow Link Issue:
Existing tiles, ramps, stairs, and similar elements across all maps have stopped working with Navigation Arrow Links.
To test, I placed new tiles, which do work with Navigation Arrow Links but still exhibit the color conversion bug.

Nav mesh generation:
After clicking the play button and then go to the map again nav mesh generation stops showing in the screen
