What can I try from here? I'm using Drupal 8.0.0-beta15.

  • Did you update from an earlier version? that sounds like a missing upgrade path, you might want to open a core bug if you can reproduce this (install beta14, then update, then all the blocks should be there).

  • @Berdir Yeah, it happened when I updated from beta14 -> beta15. I'll try to reproduce it if I got the time this weekend.
