Hello everyone!
As we’re preparing for the next expansion’s launch, we’re streamlining the Cloud Service registration to prevent more loss of data issues, therefore we ask you to LINK your Cloud Account to your Kongregate Account if you haven’t already done so. You can do this in-game by accessing the Cloud Save panel in the Save tab and pressing the Link Kongregate button.
Failure to do so will make you unable to access your current Cloud Account, a new one will be automatically created and linked to Kongregate for you once the new version hits live.
If you have any question, or in case you read this post after the expansion launch and you can no longer access your old Cloud account, please contact us via PM. Source: http://www.kongregate.com/forums/8945-realm-grinder/topics/573180-important-upcoming-cloud-account-changes
