I added a new module, it was automatically pulled into other modules. My modules would already be compiled, so I'd run `:load app/DevelMain.hs` and then `update` to rerun my Yesod application and I got the above error.

I could probably reproduce this using https://github.com/fpco/badgers if desired. `stack clean` didn't fix it, I was in the middle of something so I didn't have time to try other things.

Start with commit eeec8dfa7798175c619390e469ac5d85d6d07a6f and app/DevelMain.hs, then reproduce the failure from `:load app/DevelMain.hs` followed by `update`. If possible, try the badgers project as a smaller reproduction. Done should identify whether the failure belongs to Stack or GHC and provide a confirmed reproduction or fix.
