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.
