Wool block / carpet items generate vibrations, unless thrown by crouching players

this time i searshed carefully so i don't think this is a duplicate

It seems to produce a vibration even when dropped by the player. The only time it doesn’t seem to cause a vibration is if the player is crouched, but that seems to apply to all items they drop.

did'nt notice this

beacause you have to always sneak in the deep dark 

is this a confirmed bug??

Yes, it is confirmed. You can look at the Confirmation Status in the ticket details.

i have another question:

is assigning the ticket necessary??

If you are referring to the Assignee field, that cannot be modified. Only moderators and Mojang employees should be able to modify it.

ok thanks
