Rep system bug?

I have noticed that I can rep someone's post more than one time, is this normal? As I recall, even in the Fakku version 4 topic, it is said that you can rep a post only once. For example if I repped someone then edit my profile. If I go back to the same post again, I can rep it again. Is it a bug or is it normal?

If a post you've repped untags itself as "repped", you're able to rep them a second time. But if you refresh you find it actually removes it, so you have to re-rep them. I've fallen for this trap. Not sure if it occurs when the second rep is the opposite to the first one though.

It gets confusing when posts untag themselves like that.

So it's still one per post then, ok thanks!

I actually can -rep again if someone +reps and it sticks.

But is it supposed to be this way? More than once I mean especially less than 24 hours?

EDIT: It's seems that it's back to normal again, I can't rep posts more than once anymore.

That's the old system. Now you can rep unlimited, but one per post.
