We run a server with DW20 mod pack. We've added the items Below to it. The time was working fine, I added Bloodmoon and Zombie Apocalypse Plugins and the daytime was fine. Then I sign on one day and the players tell me it hasn't changed from Night or stopped raining the 7+ hours they've been playing. I removed both Bloodmoon and Zombie Apocalypse and the rain became fixed however, the days are still not changing on their own. I googled a bit and something was mentioned about running Multiverse...as far as I know im not unless its something that comes with DW20. I can change the time myself, its just not changing on its own.
