The player's belongings, when dying from a mace enchanted by a wind burst of any levels, fly far away, and sometimes the inventory disappears

Quite often, when killing players with a mace, if they have things, they can fly far away, or disappear altogether, which should not be in the game. The mace must be enchanted for a 1/2/3 level Wind Burst, and with a random chance, the player's belongings can fly far away/disappear at death.

What I expected to happen was...:
items must remain in place when the player dies, they must not fly far away or disappear.

What actually happened was...:
items fly far away or disappear.

Steps to Reproduce:
1. Take a mace and enchant it to a wind burst of 1/2/3 level.
2. climb high enough for the enchantment to work.
3. fall and kill the player with things from a height, the victim's things must fly far away or disappear. It may not work out the first time!
