We're seeing a lot of support tickets reporting problems that are fixs by clearing the cache. We'll gather examples here until we can find the exact bug(s), ticket more precisely, and squash 'em.
I wonder if it's possible that somehow the new layout functionality is leading to entire pages getting cached? --Ethan
Would that account for included cards that have just been added not showing up when reloading?

(It would, but that didn't turn out to be the issue).
I think we need to make a bigger priority of this. I turned the content caching back on and added a new debugging page: /admin/show_cache/[cardname]. So far I haven't heard any chatter about cache issues. But in general we should try to check the debugging page before clearing the cache.

I just added a fix that addressed the example case. Basically I made it so that all of a card's particles (eg, for card A+B+C, particles would include A, B, C, A+B, and A+B+C) have their cache cleared whenever there is a saving error on the card. There may be some more semi-obvious things like that that we're missing. The reproducible example above was highly useful for this!!!

moving this to testing because of all the refactoring that we've done (and the lack of reproducible problems to test)

Closing. I don't really believe we've fixed *all* the cache wackiness, but I don't think we have any reproducible examples of things breaking.
