Got a (heavy) plastic bag stuck in my rear derailleur of my <1 year old Salsa Journeyman Apex 1, the bag fully wrapped into the derailleur wheels while I was biking at about 10-15 mph. I had to take the whole derailleur apart to remove it. 

Ever since it has not shifted well (no matter how many times I index it) and it has significant vibration in the 6th gear (no others which is odd). I've taken everything apart and cleaned it thoroughly, double checked to make sure it was put back together correctly, replaced the derailleur hanger (although it didn't really seem bent) and triple checked to make sure the chain wasn't worn (bike has around 1k miles so didn't think it was and it was not). 

When I look down it looks like the derailleur is bent slightly inwards, could the derailleur itself have bent? Should I just purchase a new one as it seems to be the last possible variable in the equation and Apex 1x11s are around $70. Seems to be what a shop might charge to diagnose and fix this (plus I need to wait for at least a month to get to a shop.

Any help is appreciated.
