This *client* side mod addresses a bug which causes lag in mods that create custom spawners with endermen and when mapmakers or players use an endermen egg on a spawner. For example, Dungeon Crawl which we use in Two Guys Modpack creates endermen spawners.

Fixes this bug (except Evoker Fangs) which produces a lot of lag in 1.16.

Note: This bug is fixed in MC 1.17.

MC-189565 Description

Category: Performance, Rendering

Mob Spawners do not render a "mini" mob visual for the following entities:

Bee
Enderman
Polar Bear
Wolf
Zombified Piglin
Evoker Fangs

See attached images for expected (Elder Guardian) vs unexpected (Zombified Piglin). When the game attempts to render them but fails, it also produces an error message in the console over and over again, which can potentially cause a lot of lag in the world, especially when lots of spawners are used.
