I have a feeling that something is wrong with the voting on posts here.

Here is what happens:

• I wanna to up-vote some post. I'm on the post page (not the list). Initial counter is: 220.
• I vote for it and the counter goes up to 221 and shows the color that I've already up-voted.
• Now I refresh the page and it shows ... 220. It's the old number but it shows the color still, as if it was up-voted.
• Now I remove my vote and it goes down to ... 219. It's weird because it's less that was initially before my original up-vote.
• I refresh the page and it changes back to 220 (oiriginal value).

The conclusion is:

• Assumption: The values after each refresh seem to be important because all other values are volatile and can indicate a bug in Javascript. After the refresh it shows what the server has / is aware of / presents to the others.
• If I refresh with my vote (after up-voting and before removing it) - my vote doesn't count.
• If I refresh without my vote (after removing my up-vote) - my vote doesn't count.
• Considering 2 above: My up-vote doesn't count in both cases whether I up-vote, or not, whether I remove it or not.

Is this a bug or my account is flagged here as deplorable?

Do you have the same problem?
