[DW 1.20] Change sleep percentage to 50% like the other packs

[Riis]

So far this is the only CL pack I've played where the sleep percentage is set to 100%, which I assume is simply an oversight. Once you have more than 3 people online it's next to impossible to get every single person sleeping.

This was also the case in the DireWolf 1.19 server. We collected a lot of phantom membranes On the other hand, the great sense of achievement when we actually got everyone to sleep was something previously know only to parents of young children.
