I am using a custom theme for my Magento store with a bunch of custom modules. Everything works correctly 99% of the time, but I notice occasionally in the Server logs that Magento is looking in the wrong place for my CSS file, as if the theme isn't loaded. But when I visit the accused URL, it loads fine.

You can visit those URLs and see that everything loads correctly, so I'm not sure how this can be happening. Any thoughts on where I could start to track down the problem?
