I purchased the 5999 crystal pack for CX-2 when the event started on 23rd April from the webstore and the purchased did not show up in game. I was awarded 31 shards from the packs but they were not added to my CX-2 as shards.
i have been in contact with EA help through the app since this happened and they have now told be that I had to report it here as they were unable to help.
The missing shards have also slowed my progress through the “executing orders II” event and there is now w weeks work of missing rewards from that as well as the initial purchase now appearing.
