The Idea is accepted, the 'expiry time' will depends on how long you spent in server. As part of the update, we will also do some change to either the cost or duration of skin available for use. We already took count of this when we set the cost and time for skin so we might change them along with the update.
I will push the update once the control panel is working( got to wait for Thijn ).
There's some problem with panel that make us unable to stop/restart server. I can crash the server and let it starts again but i think it's better if we have the panel working incase of bug..etc.
