Update 1.11.0.9 Beta, April 3, 2019 release...

I have 9 Always Active, Repeating command blocks with almost the same commands, which I have some problems with...

kill @e[r=7,type=!player,type=!xp_orb,type=!villager,type=!item]

It was in my Advanced Skyblock Map with Trading and Conversion Structures.

Unfortunately, the insta-kill command indicated above kills all villagers since the villagers themselves got updated. I have tried to run the same command with the same command block, but have been set as Impulse and Need Redstone. I have spawned the villager on the main module of the villager summoning structure, and it didn't die. When I powered up the command block in Impulse Mode via a button, the villager died. The previous output window displayed this text...

Killed Villager.

I think it was a bug that got produced because of the villager's data update. xp_orb, player, and item in the command above still didn't get killed by the kill command indicated above.
