I'm working with the Quicktabs 2.x module, with content loaded via Ajax. When it pulls the AJAX content, it seems to bring down the unaggregated .js and .css files individually and not the advagg bundles.
Not quite sure why yet, or even which module would require a fix (this one or Quicktabs), but I thought I'd get a thread started in the event that anyone else has seen this. Should be easy to reproduce, set up quicktabs, with Ajax: Yes in the Quicktabs setup. Then click your second Quicktab and check Firebug+NET to watch the .js/.css come in for the new block.
