This isn't true, I know a ton of '0' winners who didint refund out of fear, with the news that refunding = a free house, now refunding.
it will be a very large amount in some wards with free houses.
Not that im opposed to this but im being honest here. This update was a big roundabout way of SE saying those effected by the '0' bug will get their house for free, in a very PR flowery way. As much as I see it as the only choice they could make, this will make up a large amount of affected '0' plots.
