While I like most of the game, I have to say the whole Amber bit was ridiculous, I feel it could have went down without what would actually be a company killer move. First with Mia being the one that got the other company in, doing something that would cause to lose her like that stupid move would likely kill the contract, even if Amber believed their was some fraud she'd would have wanted the notion of it silenced, not risking it being known to the other corporation, in particular not being associated with the one that signed in the deal, it would have gotten the contract ripped apart in a snap and tanked her company.
Hell the other company signed the contract with expectation of working with Mia, suddenly having her replaced by her daughter would be cause for them to break it off. Most rich people might want to put their dumb offspring in some 'visibly important, actually harmless' positions via nepotism, but even they aren't dumb enough to put their offsprings in key positions. Most of those greedy people want to make more money above all else, including family, so they won't sacrifice a great key employee just to give their job to their kid.
