The first couple of times, I thought it was my imagination, but I've had this experience likely over ten times by now.

Never happend to me O-o

That hasn't exactly happened to me. But I have found polls, a while ago, which didn't show the results of my vote even though the option I'd chosen was marked as my pick. It'd still be at 0 %. But then I just cancelled and re-voted, and it was fine.

F5 spamming seems to work fine.

Or it's just me fiddling with the code lel

That happened to me once.

off-topic but
Ymir <3

^Ymir is truly a marvel, when it comes to fictional characters. ~ ^^

She's my favorite Titan character. She and Annie.

Ymir and Annie are my favorite AoT females and third / fifth favorites in the series, overall. I can actually really relate to the both of them (but that's not the only reason why I love them :p).

It did happen to me a few times, but then I realized:
1. The question had been asked before.
2. The same question was in another fan page.
3. The same question was put under polls and answers.
Each time I was able to find my original answer when I went searching for it. I don't bother looking for the duplicate questions anymore, I either just answer it again - where ever it is - or don't bother answering it again.

Here's hoping it never does!

As far I remember,Nope it doesn't happened but i think ur talking abt that glitch in which we were not able to see our wall posts and comments? if yes,then yess,it happened to me too,but now everything is alright:))
