Tiled mosaic gallery images not loading

Hello,

Some images will not load on the tiled mosaic gallery.

It’s solved by reloading the page and I’m pretty sure every single image is on the wp.com backend, since when the post got published everything worked fine:

Even the single images in the post body are inserted as a tiled gallery to make use of the carousel feature.

An example of the problem: https://www.dropbox.com/s/uklt9rl6241vkx0/Captura%20de%20pantalla%202014-04-15%2015.35.17.png

The white space in the screenshot should be filled with images, as this other screenshot shows (the correct behavior of the gallery):

Any help will be appreciated.
