The mod's npcs did not appear one day after completing the first day of the game.

I played a cooperative/multiplayer game with my friends, the first day was normal with some errors but nothing serious

At the end of the night of the first day, no more npcs appeared in the entire game.

We have been playing the game for 17 days and we have not seen any NPC, however, the proximity alerts appear and when we get closer it turns out that there is nothing

Does anyone have a solution?
Do you know if the mod gives an error with other mods installed?
