when ever me and my friends kill this god forsaken dragon we never get any exp at all, we go up about 3 or 4 lvls but thats all we get , i thought this may because the exp is going towards armour and weapons that have mending so i decided to try kill him with no enchanted gear but still didnt get any exp, not only this but some exp is visible and cant be collected , i have tried leaving the end and it works to an extent as i gain a small section of exp but thats all, but on the rare chance i will get the normally get to lvl 40 - 55 when killing the dragon
