Describe the bug
Backpack Dissapearing when died from Ice and Fire dragon mod. When the dragon kills you, sometimes the backpack is placed next to the death point but other times backpack just dissapears. Also, sometimes, if Tombstone is enabled, when using the key on the grave, the backpack is added to the inventory but it was doing it every time.

To Reproduce
Steps to reproduce the behavior:

1. Ice and Fire Dragons mod
2. Equip a backpack (to the "back" of the player)
3. Get killed by dragon breath

Expected behavior
I expected the backpack to be placed next to the Tombstone and to my surprise, it did not.

Required informations (please complete the following information):

• Mod version: 1.16.5

I've added new config option - backpackForceDeathPlace (Default False). It places backpack straight in player's death location, but first it checks for any block that has any inventory in this place, (Mainly gravestones) If it detects this type of block, backpack is moved one block above. Backpack replaces any kind of block that is not unbreakable and has no tile entity attached.
