I'm waiting on word from the devs as I type this. That being said the only thing I can recommend right now unfortunately is to keep trying if you can repeat the quests. Do the typical cache clearing and such and check everywhere (storage, inventory, etc) just to be sure. If I hear anything I 'll let you guys know. Sorry for this inconvenience guys.
I hear that clearing cache will reset all of your E3 Quest. mean u have to do this all over again
NOT True. My ps3 froze during the media download after the Tekken quest. So I never got the statue ornament. I 1st cleared my cache, then I deleted Home and ALL Home related files on my ps3. When I reloaded Home, all the boxes were cleared BUT the Quests. It was impossible to restart the quests which involve the blue light columns.FLYING THROUGH SPACE AT LIGHTSPEED
your right the ones that involve the blue light that Christina lee sends you on will not reset. just the ones that want you to visit every booth and the one up stairs that wants you to take a photo with the mech suit and stay at the e3 booth for 2012 seconds problem is now they are not even reseting .
Right now: it unchecked "visit all booth" and almost all VIP Quest.
GalaxyGlide: Even though I SAY "I hear" = " I hear from someone" also ur right
