According to Felicia Johnson Aion US Community Coordinator, during the billing maintenance this morning an error occurred and players who applied POSA Cards didn’t receive correct rewards:

During the billing maintenance this morning, an error occurred and the bonus item now being rewarded is 2 Major Contribution Bundles instead of 2 L100 stones. This was not intended.
 
If you currently apply a POSA card, the code you receive will not give you the reward you are expecting. If you have already applied the card, and received a code and gotten the contribution bundles, you may contact customer service using this webform: https://aiononline.custhelp.com/app/ask
and the GM’s will assist you with exchanging for the proper items.
 
We are working to resolve the billing error, but it is not simply an on/off switch. I will announce when the error is resolved, so if you have an unapplied POSA card, please do not apply the code until it is resolved.
 
If you would like to keep your contribution bundles you are certainly welcome to do so. I apologize for the inconvenience!

Today, NCsoft posted a brand new video of Bard Class coming in Aion 4.0. I have to admit this class has some amazing skills.
