There seems to be an issue with items that grant creative flight (Supremium Armour, Angel Rings, etc.). When falling into the void with these items equipped, and landing on a solid platform the player is immune to all damage, and the fall damage the player would receive is "stored". The player can trigger the damage "stored" by unequipping the creative flight giving item, and falling onto a block.
