So mysterious - function within_limits() (where the error occured) uses only in api.lua itself. I wonder did you add some foreign mobs to the game?

I made an experiment with mob limits in my fork, it might help but this is odd still

No, I havent added any foreign mobs. I only spawn some evokers and vexes.

I see only 3 places where within_limits() called, all in api.lua:

-- environmental damage (water, lava, fire, light etc.)
local do_env_damage = function(self)
	...
	local pos = self.object:get_pos()
	...
	-- remove mob if beyond map limits
	if not within_limits(pos, 0) then
		self.object:remove()

-- register arrow for shoot attack
function mobs:register_arrow(name, def)
	...
	minetest.register_entity(name, {
		...
		on_step = def.on_step or function(self, dtime)
			...
			local pos = self.object:get_pos()

			if self.switch == 0
			or self.timer > 150
			or not within_limits(pos, 0) then

				self.object:remove();

-- Register spawn eggs

-- Note: This also introduces the “spawn_egg” group:
-- * spawn_egg=1: Spawn egg (generic mob, no metadata)
-- * spawn_egg=2: Spawn egg (captured/tamed mob, metadata)
function mobs:register_egg(mob, desc, background, addegg, no_creative)
	...
    -- register old stackable mob egg
	minetest.register_craftitem(mob, {
		...
		on_place = function(itemstack, placer, pointed_thing)

			local pos = pointed_thing.above
			...
			if pos
			and within_limits(pos, 0)
			and not minetest.is_protected(pos, placer:get_player_name()) then

Third part has built-in check for nul value, so it is in the first or the second one. Both are: local pos = self.object:get_pos() where self is the entity passed through on_step() callback.

I never saw this error and the only way I can imagine is if the entity destroyed during the call, but I'm not 100% sure. If nobody will have better ideas, I would merge my fix and close the issue...

Thanks for sharing the world.
I tried to run it with latest master.
I've seen dropped unknown item.
Them I was killed and there was a crash, but the error wasn't the same, probably because I haven't installed the mods: "shortnames", "test", "worldedit", "worldedit_brush", "worldedit_commands", "worldedit_hud_helper", "worldedit_shortcommands", "worldeditadditions", "worldeditadditions_commands" and "worldeditadditions_farwand". Server log isn't too big to copy-paste it right here, but I have no idea what I should do to reproduce the error:
