A projectile crash seems caused by wortox.

I have found a repeat case for this bug:

1) Kill a spider to spawn a soul.

2) Teleport away before the soul is collected but after it starts following you- timing required.

3) Repeatedly teleport away until the following soul is 64*1.2 units away and goes into limbo.

4) Wait the remaining 6 seconds before the 'miss' timer calls.

5) Server crash because the owner isn't valid anymore (soul is in limbo or spawner is in limbo/deleted).

 

This can be fixed by editing~

scripts/components/projectile.lua:167::

function Projectile:Miss(target)
    local attacker = self.owner
    if self.owner.components.combat == nil and self.owner.components.weapon ~= nil and self.owner.components.inventoryitem ~= nil then
        attacker = self.owner.components.inventoryitem.owner
    end

To be:

function Projectile:Miss(target)
    local attacker = self.owner
    if attacker ~= nil and attacker.components.combat == nil and attacker.components.weapon ~= nil and attacker.components.inventoryitem ~= nil then
        attacker = attacker.components.inventoryitem.owner
    end

 

All of the other base code makes the assumption that the attacker field can be nil so passing nil to it won't be an issue for the '.onmiss' callback.
