Subject: [PATCH] Ignore Dead Entities in entityList iteration
|
|
|
|
A spigot change delays removal of entities from the entity list.
|
|
This causes a change in behavior from Vanilla where getEntities type
|
|
methods will return dead entities that they shouldn't otherwise be doing.
|
|
|
|
This will ensure that dead entities are skipped from iteration since
|
|
they shouldn't of been in the list in the first place.
