It reverted because I fixed it manually. However, I just looked into what was really going on. It was what I suspected, so I fixed and uploaded. Now when we submit a new project, we'll see that we automatically upvoted it. This also prevents you from voting again. Before, you'd see the instant 1 up vote but you could also vote again triggering a reverse vote when in fact it wasn't one. I also added a secondary check in the script. We should be good now.

K, thx. And it seems it's already been reverted back to normal.

Fixed your project rating. I'm in the middle of coding a larger update and haven't had a chance to look into the source of this bug. I have a really good idea where and why it's happening though. I will fix.

It's something that happens often. Did you give your own project a thumbs up? I thought I read somewhere it might happen if you do that. Either way, contact Cyprezz and he should be able to fix it.
