Frequency: 3/3

CrashReporter: [Link Removed]

Regression (No) issue (does) occur in 4.10.4

Steps to Reproduce
  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
