Auto assign depending from issue type working strange

[Ars]

Hi, topic about assigning particular issue types for particular users.

I looked at article and tried to copy this:

1. Created special workflow for special issue type
2. Edit workflow create transition and added post function(update) that assignes issue type to particular user after creating
3. Published draft 
   
   Result is strange:

• User got email when he is assignee of issue type - cool
• But in the issue card assignee is unassigned
  
  

• Do you have ideas why it works like this? Thank you

This is my workflow and transition Create Issueimage2016-6-1 17:58:41.png
