What happens if I exceed 4 passengers?

[sgqwonkian]

According to the Engine Limitations at the Modmakers Guide to the Galaxy...

"WORLD_MAX_PASSENGERS 4 - maximum number of passengers that can be carried"

What happens if I exceed that number?
Will it make/allow me to dump some passenger on a planet?
Will it fail to generate the passenger?
Will it crash painfully to the desktop on picking up the 5th passenger?
Will it crash on universe creation when it loads the quest that could potentially generate a 5th passenger?

The reason I ask is that I've added a passenger or two to several mods I've posted or am working on currently, and I want to know if there's a danger that someone randomly getting calamb, mukamb, zorgamb, esmeralda and my one passenger is going to hang my mod.

If my new mod has 3 new passengers in it should I:
a) gut some original files to zap ps_takeyourpick
b) add a complicated web of KEYS to stop it at 4 passengers
or
c) just not worry about it because the game itself will stop the 5th one from generating, and do so without a crash

I think it probably just unceremoniously fails at some point. Some overflows are handled gracefully, but some aren't. Generally, they just cause crashes....often at a point when you can't tell what the hell happened

My future solution to the above problem would be to do the complicated KEYS thing, but just make it complicated enough to break the predictability (oh I got passenger X, that must mean I'll get totally unrelated quest Y) but maybe not so much as to completely randomize the thing. There are only 255 keywords allowed, after all.

It's a somewhat obnoxious challenge, because unless you do something with the Zorg or Muktians, those two passengers need always to be there. That leaves you two spots to play with.

Wow, I sure am excited for the next mod you put out, sgqwonkian. It sounds like it will be good.
