So I'm currently working on a command that will summon villagers next to an armor stand. Whenever I updated to 1.12-Pre2 I found that the command blocks were ignoring the /execute command and just summoning on top of the command block.

Example command: /execute @e[type=Armor_Stand,name=SellCropsVillager] ~ ~ ~ summon villager ~ ~1 ~

There is more to this command but I just gave you the part that isn't working.

Full Command: /execute @e[type=Armor_Stand,name=SellCropsVillager] ~ ~ ~ summon villager ~ ~1 ~ {CustomName:"SellCrops",Profession:5,Willing:1,Offers:{Recipes:[{rewardExp:1b,maxUses:2147483647,uses:0,buy:
