Adding navmesh crashes engine 4.17.1

Every time I add a navmesh and try to change the size I get a fatal error crash.link text

I have the same problem here. And i’m using 4.19.
Sometimes it drops the volume but as soon as i scale it the editor crashes.

Had a similar issue with NVIDIA VRWorks Engine built from source. Fixed it by updating VS to the latest version

Yes, in this other answerhub post I got help from another user and apparently it had to do with the building process. As i’m not the biggest expert in the matter i can’t help further but it seems to be able to be fixed -SOMETIMES, don’t wanna talk on 100%s here- by updating VS or making sure the build was done correctly.
Thanks!
