[Improved Hordes [A21.2]]

Quick question, I'm testing mods together and it would be helpful to know how long into game I should be before the first hordes come out, does it follow game day, or player level?   If I don't see any hordes by (x condition), when will I know the mod is working or not?   So far I'm like lvl 3 in current world and have only seen single zombies at a time, wondering if that is normal with mod installed. tia.

[A21 NPCMod and Addons]

Hi, I'm a big fan of the npc mod.  I used to play on a different system and it really added a lot to the game.  Now I'm on a linux system and I can't seem to get score or npc mod to work.  I get just past world creation and then the game freezes just at launch of the first person view, have to reboot to get out of it.  I may not have searched for other similar posts, its a long forum topic here. LMK if this has already been discussed.  Could do any troubleshooting or provide more information if directed, tia.

OS: ubunto 20 lts

tested with only score and npc mods. 

No errors thrown, just freeze up after map generation.
