Worker creating styles on wrong "Original"

[mccallumjack]

I posted this question on Stack Overflow but I thought it might be more relevant to ask it here.

http://stackoverflow.com/questions/32467102/paperclip-image-uploading-to-s3-with-delayed-paperclip-is-uploading-a-duplicate

Basically I have 2 images being uploaded at once into the same s3 directory, with different style_names. The upload works fine without the "process_in_backgrounds", but once they are made into background jobs, the first image is creating styles based off the second images' "original". I think I understand why it is happening, as it must be overwriting the "Original", but I'm not sure how to get around it. Any ideas?

Uploading: [A,B]

Expecting: [A1,A2,A3,A4,B1,B2,B3,B4]

Getting: [B1,B2,B3,B4,B5,B6,B7,B8]
