Really this is a question for Broonie, but thought I'd post it here so others don't ask him the same.
I am totally on board with the need to remove the extra ages created by players.
My concern is that I want to build a base in an age and use that as a base of operations. However if I do that I could potentially loose everything.
Would you consider reserving ages? Maybe a couple of ages each? Or make it a donator privilege to reserve?
If it's not in the top 50 recently used worlds, it'll be gone.
Can't allow reservations, if everyone wanted to reserve a world, it could quickly build up back to what it used to be. It was so bad the server couldn't restart on it's own, denying our early morning players the chance to play.
If you want a guarantee for your build, build in the main worlds. Otherwise, ensure your active on weekends and using your world. I think -50- worlds is generous as it is. If it's used, it'll likely stay, if it doesn't, it'll go.
If your active, it shouldn't be a problem.
How often will the worlds be removed (sorry if you've already said at one point , is it weekly or every restart?)
Look at forthcoming events, it says when.
