Nova Crawler-only rounds

[cowboymode]

So I've been messing around with modding for the last few weeks and I think I somehow enabled Nova Crawler only rounds. I've never seen this before and when I google about it nothing relevant comes up. Am I just crazy and these have always been a thing? Also, to clarify, these are rounds where nothing but Nova Crawlers spawn for the entirety of the round.

These are the files I've edited so far but I don't recall seeing or changing anything related to this...

Any ideas? Thanks!

Maybe trying narrow it down by checking which file that enables it. Then look at the source code carefully.

WolflexZ Okay, but have you heard of it before? I know how to disable/enable nova crawlers in general, but these nova-only rounds don't even seem to exist.

I've already tried removing this ITE without any noticeable changes:

	level thread players_playing();
	if ( IsDefined( level.crawlers_enabled ) && level.crawlers_enabled == 1 )
	{
	    level thread crawler_round_tracker();
	}

This is from _zombiemode.gsc.

I even completely reset the _zombiemode script at one point just to be sure any potential changes were undone. Looking at other scripts, the _zombiemode_ai_quad script doesn't mention anything about these special rounds, and I know all I did there was modify the gas cloud to last shorter. The rest of the scripts are completely unrelated o.O
