I'm not sure but I think this could be a bug? 

Anyway, when a suggestion gets implemented or closed because it's a duplicate - the votes should be automatically returned to the users. However, right now the votes just become frozen and we have to wait weeks to get more votes.

I reported this as a bug a while back and Ji-N did a work around to just increase the users' # votes over time instead. I'm not sure if he is planning to change it eventually or not. 

We will move away from this system eventually, but you do get new points every week.

You'll remove the Suggestions section? :/

No, just the way the points system work.
