LEGO CITY Undercover

Achievement will pop after finishing Special Assignment 14: Blackwell Mansion.

This might help people who same as me did not receive the achievement for complete the chapter. Actually I came back to the game at beginning of chapter 13, I saw chapter 14 started but did not received achievement for 13th, but I did not care because I thought it will pop later, I finished chapter 14 and same no achievement. Here is what I have done:
- I turned off game,
- Restarted Xbox
- Turned off Xbox,
- Unplugged Xbox and wait like 3 minutes
- Plugged Xbox
After these steps I launched game and completed chapter 15, and received achievement for chapter 15, but still no achievement for 13th and 14th, YOU CAN NOT REPEAT CHAPTERS you can only replay Special assignments so I decided replay Special Assignment 14: Blackwell Mansion, after I left the mansion the achievement for complete chapter 13 popped!

Good luck!
