Description

Certain characters within blueprint variables names will cause data loss when duplicating an actor instance. For example if a variable name contains '(', '{', or '[' it doesn't retain the variable's state when duplicated.

Steps to Reproduce
  1. In the content browser create a new blueprint class with an Actor parent class
  2. Open the blueprint and add a new variable (of any type), I'm using a bool in this case
  3. Name the variable: temp(
  4. Mark the variable as "Instance Editable"
  5. Compile, save, and close the blueprint
  6. Drag and drop the blueprint actor into a level
  7. Check temp( to true on the blueprint actor
  8. Alt + drag (or copy + paste) the blueprint actor to make a duplicate instance
  9. Note, the value of temp( on the new instance is false
