This freezes the game in its tracks. Mission becomes uncompletable, it literally can neither pass nor fail on mission stage with even the slightest glitch, as you can't tell the game not to hire a tiger team.
I was just 22 in the red. I don't even know how I got in the red, my balance was positive. Must've been personnel training.
I humbly suggest that you allow the "Don't hire tiger teams" option to always be selectable. Maybe widen the range from any number >0, to any number of available funds.
