I'm the author of Millénaire, a mod that adds villages with human villagers that I've recently been porting from 1.7 to 1.12. More info here: http://www.minecraftforum.net/forums/mapping-and-modding-java-edition/minecraft-mods/1272755-millenaire-npc-village-new-villagers-in-players
As several players have reported and as I've just tested, your probe mod acts like some kind of death ray on my poor villagers The second the player's focus is set on a villager with your mod active, the villager disappears, at least client-side. There's nothing in the logs. Any idea what could cause this? Thanks.
