Votes are weird. I'm commenting on this post on lemmy.dbzer0.com, and the vote counter shows 13. But when I mouse over it, it says 167 points - 167 upvotes - 0 downvotes.
On its original instance, kbin.social, I see that it has 6 "favourites."
Coming back to the dbzer0 tab, the point total now says 2 and mousing over shows 13 points - 13 upvotes - 0 downvotes. That sounds more reasonable, but where did the other number come from? Why doesn't the displayed number match the mouseover text? Who knows!
