Interesting, are you sure its more of a peanut buttery taste or is it more of a yeasty/doughy taste?
Also, if the crack has been letting air in that does mean theres a possibility of infection, however it may be fine. Have you tried anything to see if air is getting in through the crack in the lid?
My guess is, FWIW, if no air is getting in/out from the crack in the lid and you sanitized properly then all will be well. In other words, RDWHAHB
