This was the simplest solid repro I could get on this bug. The callstack is similar to [Link Removed]
Also came across several Shader Compiling Manager crashes while attempting to repro this crash but no repro ever worked twice like [Link Removed]
This does NOT happen in 4.14.2 so this is a Regression
Repro using regular materials:
Result: The Editor crashes
Expected Result: The material successfully deletes
-------------
Repro using Landscape
Result: The Editor crashes
Expected Result: The material successfully deletes and the landscape goes back to default material
