I see...
But keep in mind that mentioned game instabilliy is not caused by simmple mod conflict or faulty modlist, I can conform that for sure.
In short, type ll has pretty much the same effect on game as tdw sub flags do, where mod created by the book can crash good modlist if "enough" units/objects has been rendered.

Unfortunately, this also true for some ohll dat airplanes, like b17 and p47,in-game submarine bunkers, AI sub crew mod, sub smoke exhaust and even for player subs it self.

This is the proplem caused by unpatched game engine and it can be amplified by mods which can misslead many that the issue is actually caused by some mistake in their modlists...
