When can we get a credit boost day like before?

I remember a few times Winter that you increased the amount of credits we could receive depending if your donator or not and I would like to see that again as soon as possible. In light of the summer update coming we should get a chance to rack up as much credits as possible for when all those new things get added to the server. Let's be honest we all enjoy those extra credits as well! When can we expect something like that to return?

I do it every now and then. Maybe we'll do it as a part of the Summer Update for a week or something.
