Description

Modifying a UserDefinedStruct can lead to data corruption in Blueprint array properties.

Steps to Reproduce
  1. Create a UserDefinedStruct with two int properties "MyStruct"
  2. Add an array property of type MyStruct to a Blueprint
  3. Compile, add a few entries to the array and set values for each entry

  1. Add a third property to MyStruct (I was able to consistently repro using a float)
  2. Recompile the Blueprint and note that some of the values in the array entries get stomped.
