I am developing a datapack for a modpack using Exposure on 1.20.1 Forge. With it, I am attempting to require that players get within a minimum distance of mods to get a valid photo for the advancement. However, the game ignores the distance property for entity_in_frame, and always acts as if the player/mob is within correct range at all times.
Here is a gist file of what I'm trying to do.
While I found this via developing a datapacck, this can be demonstrated by testing the Exposed Paparazzi advancement. If all other conditions are met, the advancement will be granted, regardless of distance to the Villager- the advancement still fires even if you get up in the villager's face.
