Hello good. I have a Minecraft server with a modpack, and among those mods is The Hordes. The first days of the world, the server is fine, but day X arrives and it try to launch a horde, and then it crashes, and if I start it again it crashes again. In the debug.log it tells me the following:

[15nov2024 20:42:15.757] [Server thread/ERROR] [net.minecraftforge.eventbus.EventBus/EVENTBUS]: Exception caught during firing event: Cannot invoke "net.minecraftforge.common.util.NonNullSupplier.get()" because "other" is null
