So for last week i've been using:

@SubscribeEvent
public void onWorldTick(TickEvent.WorldTickEvent event)
{
	for (Object o : event.world.getLoadedEntityList()) {}
}

And today launched Dedicated and noticed (server crashed) getLoadedEntityList() is @SideOnly(Side.CLIENT)

 

I tried finding some similar method in WorldServer.class but anything close to one above is list by UUIDs.

 

Anyone knows how to get all entities (or at least EntityLivingBase) in server world? - ***From world argument***

And it is this moment that I am 100% certain that I need to (finally) go to bed.

 

...I am blind...

 

Btw. why the hell an universal (both-sided) field has getter only for client? I mean, seriously, why would you do that...
