When a player goes to sleep in a multiplayer scenario, the message displays the following:

<player> is sleeping in a bed. To skip to dawn, <number of non-sleeping players> more users need to sleep in beds at the same time.

This differs from the typical wording of Minecraft, which would say this:

<player> is sleeping in a bed. To skip to dawn, <number of non-sleeping players> more players need to sleep in beds at the same time.
