How to reproduce:
1. Open “ConstructMatrixBug.zip” project
2. Open “OutdoorsScene”
3. Observe the Console window for warnings
3. Make sure the “Construct Matrix” blocks are present in “MagicMissile.vfx” and in “UpForwardPositionToMatrix.vfxoperator” Assets (Check internal notes on how to create these if they disappeared)
4. Enter and then Exit Play Mode
5. Observe the Console window, “MagicMissile.vfx” and “UpForwardPositionToMatrix.vfxoperator” Assets

Expected result: No warnings are thrown in the Console and “Construct Matrix” blocks stay in place
Actual result: “Construct Matrix” blocks disappear and warnings are thrown in the Console
