#Fixed: if all players of a world slept at once, night was not skipped every time.
I have planned some more features and hope to get them implemented within this week. Unfortunately this bug quite got me but it should be fixed now.
Although it is still supported it is not recommended to use any other plugin to set a player sleepingIgnored (essentials etc.) because this behaves the same way as there was no player at all what brings us back to the problem of instant night skipping.
Let me give you an example (needed sleep percentage is set to 50%): If two players are in a world, one is sleepingIgnored by essentials, one not. If the first one decides to sleep in a bed, everything works as it should: night-time speeds up and he will wake up eventually. But if the second player decides to sleep, he will get kicked out of bed and therefore night has to be skipped instantly.
I will edit the plugin's main page on spigot in the next view days.
