Logged out, back in, re-fetched Grapevine listeners and re-calculated all and it works now!

The first time through I had left one of the listeners on, and when I did the calculations they took a long time and I refreshed a few times. maybe I corrupted the database.

I know you've got a ton you're working on, but something to toss on the TODO heap for (much) later would be stronger guardrails during onboarding so new visitors don't shoot themselves in the foot like I did :)

Thanks again!
