  • EUS Matt.Williams - Add one sample to a 1D blendspace. Right click the sample, clear the animation
Steps to Reproduce
  1. Create a Third Person Test Project
  2. Create a 1D Blendspace
  3. Add an animation sample to the blendspace graph
  4. Right click the sample point in the graph
  5. Select the Animation Dropdown>Clear

Result: Crash
Expected: Animation is cleared and sample point turns red
