We've patched a bug that caused some bosses to be unable to spawn portals (or do other things) when they die.

There's another bug I've seen reported a couple times which I can't reproduce in a development environment: some people are seeing no clue-runes in War Caches, the little plates are just empty. If this happens to you, please try relogging and seeing if that fixes it. And whether or not that fixes it, please let us know in a bug report! Please report the results of your experiment whether it fixes it or not. That'll help me understand what sort of problem it is. Thanks!
