I've been running a server for a while and noticed how incredibly easy it is for all of us to just go to bed every night to make it day again, so we never have to deal with monsters. I think it would be really neat if there was a configurable chance that a night could become a sort of "deadly" night where you couldn't sleep to skip it. This would not remove the use of beds entirely, but would limit their use and make it so sometimes you would have to deal with the night. I can't really think of a logical, realistic reason as to why you wouldn't be able to sleep certain nights, but I'm sure somebody could come up with something. Either way, I would love to have a plugin like this
Maybe sleeping just regains health instead of skipping night. Im sure there is a plugin, or if you look deeper in the config files you will find a setting for that
