Up/down vote buttons for post intermittently do not register

[amicitas]

Describe the bug When I press the up/down vote button for a post my vote usually does not register. When I press the button it highlights as expected but when I refresh the page, the vote dissappears. After a few attempts at voting and refreshing eventually the vote will register.

To Reproduce Steps to reproduce the behavior:

1. Vote for a post in the subreddit page or comments page.
2. Refresh page.

Expected behavior Vote registered and is displayed after page refresh or moving between pages.
