Ender dragon

(forgive me for bad grammar because i'm a bit autistic) If you're battling the enderdragon in the minecraft bedrock edition, you'll encouter a bug (i think it's bug) of fighting the enderdragon. You see, whenever the enderdragon spits/attacks you with his projectile acid, it may seem normal/fine but later on in the fight you'll see that it's bugged, i took damage from the invisible projectile acid without seeing, i'm not sure if it's because of the render distance of within the settings or if it's actually a bug, or something because of it, i even died from the invisible projectile and, not even the totem of undying could save me, so. I went back into the end, grabbed all of my stuff and continued to fight the enderdragon. while in mid fight, i started to notice that the acid projectiles started bugging out and the particles seem to be just stay, and not fade out like they're supposed to. then, i started taking damage from an invisible force (like i stated previously) i was getting confused and getting a bit mad because, like i said i was taking damage from an invisible force. i managed to defeat the enderdragon in relief. but when he didn't drop any XP it all went down into the overworld teleporter. i stood near the overworld teleport hoping i can get the xp. but nope, so i went down there. and when i returned NOT EVEN A SINGLE XP DROP AFTER DEFEATING THE ENDERDRAGON. i was so mad. that i just quit the game. and now here i am typing this out please. fix it..
