I've implemented the Credits Premium addon roughly 2-3hrs ago. I've created a bunch of events and all seems to work pretty well so far. However, out of nowhere, I noticed that an user had 48 gold (my currency). Investigating that user, I found that he was registered somewhere in 2013 but his account was not even confirmed...so basically, it was a ghost account. Is this a bug? How can I identify the issue? I'm not sure if this bug appeared when i upgraded to 1.6.0 and gave me that weird mysqli error.
