Geometry editor crashes when applying

The geometry editor crashes for my maps when I try to create a brush when I click “Apply”. This happens only with my landscape objects which I imported from a heightmap, not when I use the function on another landscape.
Since it is hard to reproduce, I give the link to a sample project where the crash happens.

Load the map under Client/Maps/SS1/Sublevels/Col_13/Row_12 (it’s the only map there)

Go into top view, click on the landscape, activate Geometry Editor and click on “Pen” mode

Add a few vertices with “Space”

Close the shape with “Enter”

The Editor will crash

I found a post here where a user had the same problem and found a trick how to avoid the crash, but you weren’t able to reproduce his bug on your side. Hopefully with my project you can debug it

Hello ,

After taking a look at you project I was able to reproduce this issue on our end. I have written up a report and I have submitted to the developers for further consideration. I have also provided a link to the public tracker. Please feel free to use the provided link for future updates.
