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

Dying in the End void does not have the same behavior as dying in the Nether or Overworld
