I tried debugging this, but I had to leave early for a dinner date.

I believe the Node in the iterator of ScriptLoader#loadItems(SectionNode) is null obviously, but I couldn't figure out why it was being null. The traces lead back to the SkriptParser not parsing the expression correctly, because SkriptParser.validateLine should catch and continue if the line is invalid, but it bypassed that check somehow, which then lead to the SkriptParser to return null and causing the whole spiral after that.

Could be due to the multi condition where filter lambda [example]->[example2]

This is also used in a function

function zombiezLeave(p: player):
	delete {npcnetwork::player::%{_p}%::game}
	set {_map} to {zombiez::player::%{_p}%::map}
	subtract 1 from {zombiez::map::%{_map}%::players}
	loop all players where [{zombiez::player::%player input%::map} is set]:
		if {zombiez::temp::player::%loop-player%::dead} is not set:
			add 1 to {_alive}
	if {_alive} is not set:
		set {zombiez::map::%{_map}%::players} to 0
	teleport {_p} to {zombiez::spawn}
	loop all players where [{zombiez::player::%player input%::map} is set]->[{zombiez::temp::player::%player input%::dead} is not set]:
		add 1 to {_alive}

My build is nothing changing. It's basically the master branch as of right now.

Which addons are you using?

SkQuery, but the error is coming from Skript's own SecLoop
