I was playing around with some stuff and i wanted to see, if a thrown enderpearl triggers a redstone hook, and it didn't. Instead, i stopped right at the string and therefore triggered it myself. I did some investigation if it could be me just hitting something like the floor or so. I digged out a big hole and 4 blocks up in the air i put the strings and hooks. I throwed enderpearls from the sides and that stopped me aswell... Then i tried to do it from beneath, and it again stopped me at the string.

Important thing!!! I won't say that this should be fixed or not, because mapmakers will maybe learn about this trick and use it like you get some enderpearls and then you need to throw you through a lot of stuff and then it uses this thing and say ''Did you really think you could do this?'' or something... idk
