occured when teleporting to different level in the level streaming mechanism.

Hi mirsabayu,

Does this crash or is it just producing the error? Does anything else occur when you teleport?

it’s crash. that report above, i got from visual call stack. and also in the editor screen it inform that the navmest need to be rebuild.

Is there a navmesh in the level that you teleport to or is there no navmesh at all?

Hi mirsabayu,
