quoting Izambri:

Hmm, wait...

What happened 11 hours ago, when a bunch of changes took place in different universes and dictionaries at the same time (it seems) with no change in 'size' (all changes are marked 'size: 0')?

Is it related with some misteriously erased stuff in my (and perhaps others) universe?

Oh god—shit—yes. I'll try to restore from backup. I blew them up while working on the new stats counters that appear in the universe index; = instead of ==. Thanks for pointing it out.
