I am using a recast graph which is cached and when using the RVONavmesh script for walls, it seems to re-scan which causes major lag (less than 10FPS) for 30-60 seconds and then FPS goes back to normal (60FPS).
I checked the profiler and it said WaitOne() was causing it (~150ms CPU usage).
Is this a bug? If not can it be pre-cached with other cache or?
