PollUnit in Slack errors when changing vote to 0

As a voter in a dot voting poll, I need to change my dot selection from a number to 0, so that I can add dots to other choices.

When I do this, this is the error that's presented and the poll disappears:

Couldn't find Option with 'id'=0 [WHERE "options"."poll_id" = $1]

Hi Monica,
Thank you very much for reporting this!
It is fixed now and you can vote with 0 now from slack.

Kind regards
Philipp

Nicely done Philipp! Thanks a ton.
