Probably a site change..

Anyway, might be time to consider authentication support for VK. You need to be signed in to access certain groups, galleries. etc.
I think there's actually a lot of interesting content which I believe is originally from there.

No, that's a bug. It treats /album221469416_00 the same as it would /album221469416 even though they need to be handled differently.
