Map crashes on load re: Instanced Meshes

I have an issue where a map I was working on now crashes on load.

I had recently added a terrain mask painting layer to the terrain and was doing some height and mask painting. I noticed that the instanced meshes had been duplicated in the area I was working on. (same meshes at two different heights) and so I saved and restarted the editor hoping it was a caching issue. Instead the map now crashes on load:

Any help would be appreciated.[link text][2]

Hello,

This sounds like a known issue: Unreal Engine Issues and Bug Tracker (UE-32774)

This was fixed in 4.13, so you should be okay if you upgrade a copy of your project to 4.13. Alternatively, you can grab the commit from the link I provided and merge that into your engine if you are using a source build from Github.

Have a great day
