I was updating my tombstone datapack to 1.20 when i noticed a weird behavior.

Steps :

• Trigger on death
  • execute as @a[scores=
    {tombstone=1..,hp=1..}

    ] at @s ... 

• Summoning pos marker into the dimension
  • execute in ... run summon ...

• Find place & Summon the grave
  • execute as 'pos_marker' at @s ... (searching stuff)
  • execute as 'find_place' at @s run function tombstone:create/place

Expected behavior :

• Working in every dimension, even if player fall into the void.

Current behavior :

• Working in every dimension, even if player fall into the void exept if player dying into the end void.

Explication :

For an unknown reason, spawned entity during the process are not detected with @e selector if, and only if, player dying into the end void from the Y level that does the damages.

Tests :

• Rewriting the datapack using others techniques : Same issue.
• Test others dimensions : Only end is affected
• When player are below Y:-65, tp at -30 and killing them : Working
• Tested in loaded & unloaded area (forceload command) : Same issue
