Invisibility commands on armor stands makes an issue.

Using invisibility commands on armor stands makes the armor stand constant move along side you. This is especially infuriating for those who are map creators because we experiment with all kinds of commands which make a cool experience for us. This is instantly ruined for me when an armor stand is constantly stalking me. If you go into game and put an item in an armor stands hand then make a repeating command block with this command inside

/effect @e[type=armorstand] invisibility 1 1

You will notice that the Item in the armor stand's hand will follow you.
