Yup, I was able to recreate the issue... It is most definitely the Low user priority, the server is set at. It'll probably take on average,,, 8-15 minutes sometimes, for some post. I'm pretty sure it may even matter how many people are looking and responding to the post at a given time. I.E. You won't find the problem quite as often in threads of Spam or whatever... That's my conclusion on that.

That's something that Mahz put into place. It is annoying... particularly because it effects avatars and that's what people complain about first. XD But, he has his reasons for it. All I can say, is be patient for now. You have to remember, that this place is still under construction.
