Crash when objects with Erase blend mode duplicated
- 
					
					
					
					
VectorStyler version: 1.2.042
How to reproduce:
- draw any shape
 - in Appearance panel -> Fill -> Opacity, change blend mode to "Erase"
 

- Duplicate by opt-dragging
 
This reliably produces a crash. I've tried a variety of other blend modes and those are OK.
