I’m using UE 5.2 and apparently, this bug still happens. DmitriAzimov’s solution still works too! But, note: At first, I was confused and deleted my NavMesh Bounds Volume, and didn’t delete the associated RecastNavMesh. This did not fix it. That is, I had to also delete the automatically-generated object called RecastNavMesh-Default, and then the problem was fixed. Thanks again to @DmitriAzimov !
