Not sure if that relates since the projectiles spawned several blocks away.

Can confirm in 21w05b. Haven't seen it yet in 21w06a, but that's not to say it's fixed.

Major bug for pvp and pve, refered to by most players that experience it as "Ghost Arrows".

This also happens with any projectiles, not just arrows.

Confirmed in 24w07a

Can confirm in 1.20.5-pre1

{*}{*}Can confirm in 1.20.5 & 1.20.6-rc1

Can confirm in 1.20.6 and 24w20a

can confirm in 1.21 through to 1.21.4
interestingly - in 1.21.2+ when this bug occurs, the game summons a "ghost arrow entity" where the arrow appears to bounce off the entity it ghosts through, but then the actual arrow entity reappear to have landed where it should be
