This has started to happen to me recently as well. It's scary because 99% of the artifacts from your storage are gone (sometimes a few new ones remain for some reason) and they're all gone from all characters. This also affects the champion's power display in character storage and on dungeon/pvp screens, which scared me at first because it didn't seem to be a simple graphic bug where the artifacts were eqiupped, but unseen.
Thankfully, your artifacts are not gone and your characters do not appear to actually lose any stats as it would appear on screen. Closing the game client and restarting should get everything back to where it should be.
