If Spencer is dead, you can't even finish 
the game. And if Pendragon is hostile, 
you should die at gate.
The best fix would come along rebel 
faction, but thats not for 0.16

I propose to add a Radar sensor to 
Pendragon, Bender and Spencer so they may 
kill Tux if such thing even happen. And 
temporaly make Tania and Doc unable to 
heal, maybe? This is my proposal.
Otherwise, we have the HF non completable 
problem, which imo is much more 
important.
