We are aware of the gold exploit feedback that has been circulating social media and the forums. At this point, we are working to get a hotfix put together as soon as possible. A rollback will not be necessary at this time; the current scope of abuse is not outside our ability to manually correct where necessary. Please understand, if you have abused this exploit, we will be taking action against your account. As you all know, we take exploits seriously and will not hesitate to lifetime ban accounts that have been caught abusing any exploits.
That being said, if you have used this exploit - you have 24 hours to contact Customer Support. They will confiscate your exploited items and reduce your punishment. This is a one-time offer, I suggest you take it.
I will be posting more info as I have it.
UPDATE 8:45pm PST: We have disabled gardening in order to prevent further abuse. Read details here.
