Not sure what the common thread here is, but essentially I have been updating/editing cards, then hitting save, and the update is not reflected. Thought it was specific to enclosures, but noticing that it is all entries.
Sigh, I hate this bug. I think it's a javascript issue, but it's quite irregular and therefore hard to fix. We're planning to do some refactoring that will solve the issue through a broader, more robust reframe.
