Is it the mod that changes the crew recruitment system? Because if it is, there is a huge glitch/exploit:
You can hire kerbals with a negative cost, effectively gaining money.
For example, you can hire a kolonist with courage 0 and stupidity 100, level 2, for -42.000 funds !!! Curiously, increasing the level gives you more money.
Bulk hire selector at 10 allows you to gain up to 420000 funds with ONE kerbal. ps: can anyone explain to me what does the bulk hire selector does?
