So....the Malak rollback was messed up.

I had a similar problem except that I never activated Malak after completing the event when it wasn't bugged (I think it was the second time the event showed up). After completing the bugged event I got the extra shards, but with the rollback they took away all my shards and now I can't activate Malak or get the rewards from the event. My support ticket response was that I was bringing up an issue with Malak gear and did not address the issue of missing shards that seem impossible to get now. We'll see if my response clarified anything for them...
