Cannot read block headers' entities after changing their order

[erfansn]

I realized that when changing the drawing order of entities, I cannot read them properly, and some are missed. If this isn't a bug, how should I read them in order?

auto currentEntityObject = get_first_owned_entity(blockHeaderObject);
while (currentEntityObject != nullptr) {
  ...
  currentEntityObject = get_next_owned_entity(blockHeaderObject, currentEntityObject);
}

I reverted this line of code, and it worked perfectly afterward.

The question is: Why did this change occur?
