Specialized Creo clicking

Talked to bike shop today. Specialized said to file a warranty claim. Want pictures of bike and serial number.
Shop just installed new motor. Seems to have fixed noise. Only problem is I threw chain off front chain ring when climbing hill. Shop said they didn't do anything to cause this. I've had the bike a year and never had this problem until first time I rode after new motor.

Has the Shadow derailleur clutch been on?

No, my bike didn't come with that. The guy at the shop just showed me that yesterday. Looks like a good idea but there something else going with the rear cassette since the chain wants to move to next sprocket on the last two.

Wrongly adjusted derailleur.
 
Heard back from shop yesterday. Tech talked to Specialized warranty support. They said to file a warranty claim for a new chainring. I just find it weird that I never had this issue until motor was replaced. Tech compared my bike to new one everything is the same.
 
Problem solved. It turned out that the inside portion of master link on chain had very slight deformity. Replaced with quick link. Everything is good.
