Yes, it's kinda sudden but it is to get more consistent upvoters (like you) to upvote for the post and pust the reward pool a little higher. 2nd chance people only have 48 hours to claim, thus its a nice way to filter active users. If no claims are made by then, the next participant i.e. you, will get the reward. We'll revert back to old rules if this doesn't work out. Lastly, thanks for your upvote.
