NB : note that MC-140973, MC-140759, MC-140975 and MC-143112 are very similar issues. They are all due to mistakes made when creating village's structures or arranging those in files where they shouldn't be.
As there is a lot of duplicate file issues, I thought that it could be a good idea to merge all these issues in one (more clarification, and easier to fix).
The structures include:
For the snowy village:
minecraft:village/snowy/houses/snowy_butchers_shop duplicates minecraft:village/snowy/houses/snowy_butchers_shop_2, but has no jigsaw block nor smoker (so doesn't generate naturally)
For the taiga village:
minecraft:village/taiga/houses/taiga_sheperds_house_1 duplicates minecraft:village/taiga/houses/taiga_shepherds_house_1, but has no jigsaw block (so doesn't generate naturally)
minecraft:village/taiga/houses/taiga_weapon_smith_1 duplicates minecraft:village/taiga/houses/taiga_weaponsmith_1, but has no jigsaw block (so doesn't generate naturally) (was first described in MC-141007)
minecraft:village/taiga/houses/taiga_decoration_1 duplicates minecraft:village/taiga/taiga_decoration_1 but is in the wrong file
minecraft:village/taiga/houses/taiga_lamp_post_1 duplicates minecraft:village/taiga/taiga_lamp_post_1 but is in the wrong file
minecraft:village/taiga/houses/taiga_meeting_point_1 duplicates minecraft:village/taiga/town_centers/taiga_meeting_point_1 but is in the wrong file
19w06a update :
minecraft:village/desert/houses/desert_blacksmith_1 duplicating minecraft:village/desert/houses/desert_weaponsmith_1 was fixed (the file was deleted)
minecraft:village/taiga/houses/taiga_armorer_house_2 duplicating minecraft:village/taiga/houses/taiga_armorer_2 was fixed (the file was deleted), however this is inconsistant because the first armorer house is named taiga_armorer_house_1
