Added this mod to the Vanilla Perfected Modpack. No matter what my configurations are, there are no signs of any horde nights, or any announcements of an incoming horde night. I have confirmed the presence of a horde zombie, as I have died to a singular one, but there is no sign of any significant gaggle of them spawning at night.

I have added no other mods to the pack aside from Undead Nights.

I don't use the Curseforge launcher, but I hope it will help, when you provide the log with debug messages enabled :)

Can you please set the option "printDebugMessages" to true, let the game run for 1-2 minecraft days and post the log output. Thanks.

Are there any tick speed changing mods in the modpack?

Perhaps I messed up my profile?
I've included a file code of my version of the profile from CurseForge.

Thank you very much for the help.

I will provide the logs as soon as my schedule clears up

I just did a very quick test:

• I did a fresh install of the Vanilla Perfected modpack
• installed Undead Nights
• created a new world
• waited 5 days (default setting for the horde nights)

--> and hordes started spawning

so it seems to be a config issue on your side, I can't figure out what yet though. I hope to know what is going on when you provide the config.

Please note: be careful with the "persistentMobs" config option, this meas the mobs will never despawn and the count towards the hordes mob spawn cap

Well, I just installed the CurseForge Launcher for a quick test. I imported your profile, started a new game and Undead Nights works without a problem...

any update on this?

I assume it's working now :)
