Troops are useless

[GuyOfDoom]

It came up in a recent game of mine. SEV v1.33 w/ BM 1.03a

Basicly it was discoverd that if you load fighters into a cargo bay you can drop them off on a planet like troops and you can capture the planet.

I had weapons platforms, but they appearred to do nothing, which I assume is a seperate bug.

The question is this: Why if fighters can do space AND ground combat would you EVER build troops?
