UnionPack 1.2.0

"The Hordes" removed, as the mod runs asynchronously on servers.

"Undead Night – Zombie Horde Night" added.

Every 14 days, there is an 80% chance for a blood moon to occur. During a blood moon, zombie hordes will spawn and attack you. (The 14-day cycle only starts counting after day 7.)
