Ice Spear of Splitting projectiles glitched in mid air causing extreme lag

I was doing a blight map when somehow these projectiles got stuck in mid air and as a result the map got super stuttery and my fps permanently dropped by 115 leaving the map or switching to other zones did not fix the low fps only restarting the game did
