Not sure if this is a related issue to #13 with the TRPC?

[samajammin]

Ah, I'm guessing this might be because my address is not a badgeholder. Is that correct?

It's checking if you're a badgeholder before this error is thrown. It occurs when signature of the ballot doesn't match the store ballot for the user. Not exactly sure why this is happening. It's also mentioned in #6.
