What is a cargo ability?

What is a cargo ability and what is a loading ability? I read it from Elil's WE FAQ says "Give a unit a loading ability without a cargo ability" will crash the game. Can someone give me a example? thx!:foot:

Um, that's quite obvious, Izualism. If you want an example, make a unit with Load and don't give it cargo, then have it go load something. Voila, instant crash.

Essentially, the load ability lets units pick up other units. This includes Devour - you'll need Devour (cargo) in order for the unit to "eat" another unit. Technically, it's loading a single, enemy unit and damaging it over time.

OMG! From the description he gave from the FAQ, I NEVER would've guessed that it meant that! 0_o

But seriously... what else would it mean? Giving a unit the load ability without the cargo ability will crash the game... I don't think it can really get more self-explanatory than that. :bgrun:

The load ability makes a zeppeling / boat be able to pick an unit

the cargo ability is the space where the loaded units are stored
