Navigation bug causes crash on sloped bsp?

Hi all, I’ve got a crash whenever I move my aicharacter down a sloped path, where slopes merges back to a flat surface. I’ve attached a picture. When aicharacter reaches circled spot, where nav mesh changes shape, whole editor crashes. I believe it’s a bug with navigation system, though I know next to nothing about navigation besides how to generate it and add a volume for it. Everything works fine when I use stair bsp’s and such, but just at this spot it crashes. Maybe it has to do with way nav mesh wants to smooth out angled shape?

Hey ridley075,

I tried reproducing this issue in 4.5 but didn’t have any trouble. Which version of engine are you using? Please and attach crash log and dump file for your project after this crash. Thanks!
