Frequency: 3/3

CrashReporter: [Link Removed]

Regression (No) issue (does) occur in 4.10.4

1. Open Editor (any project)
2. Modes>Landscape>Create new landscape>
3. Open Level Blueprint
4. Create blueprint in attached image (RMB>Promote to variable on Editor Apply Spline>In Spline Component for spline component variable)
5. Compile
6. Press PIE

Results

Editor crashes

Expected

PIE starts, landscape is deformed around spline component location.
