The players are the ones that are forcing you into this and costing you 2k not BW. Also hard to foresee everything that a player would do to just agravate others.
Now knowing this maybe BW should put in the game were someone infected cannot get on fleet or off the planet until they are cured. Something along the lines "Due to the rampant spread of the infection all ports leading off the planet are closed until you are clean of this infection".
Actually I was hoping it flagged them red so you could kill them on sight, just like the "sprecial order" recommends.
