Quest blobs aren't syncing correctly [5.056]

[flatluigi]

When I click a quest to watch in the Carbonite quest tracker, it doesn't sync correctly with the Blizzard tracker and no quest blobs show up on my minimap. It works if I watch a quest directly through the Blizzard system, but that's obviously suboptimal. :v Anyone else having this issue?

Standard troubleshooting: I've reset Carbonite to defaults, doublechecked all the options in Carbonite, and tried it with Carbonite as the only addon with no result. Trying it with no addons enabled at all works fine, so it isn't any misconfigured game option.
