i;'m running beta 249 and i'm seeing this often.
i'll refresh and it comes out odd.
i've tried it with default parameters, out of the box, problem persists.
i then tried limiting connections and such, trying different things but same thing.
I have 2 different ISPs, hence two ip addresses i can play with and externally the page wont load right, it seems to not load header logo sometimes.
i've tried the rawr, thunder chicken and i see this often. but if i use the default hfs template, or hfs damn, and beta black i rarely see the problem
it seems to be related to the bigger templates like rawr n such.
when i use hfs damn or the basic one thats comes with hfs, i dont think i've ever seen it not load right.
so perhaps the themes are not compatible with 249 and such.
maybe dunno just throwing ideas out there but i'm clearly seeing the problem and i've tried various combinations.
i'll test it more, but i think it happens more locally then from an external ip.
