Hi mirsabayu,

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

3

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.

4

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