I am Jarne and i think i found a bug.
I was raiding the end (killing the dragon) but i was not able to kill it.
I could only do damage with bow and arrow but not with my sword.
As i was trying to kill it i saw some particals.
(I am realy upset because i have put 40 hours into my world and i can't kill the dragon.)
Please help if it is not a bug.
