I try to think logically, if it does go to negative then what's the point of having it on positive?

If I can keep using morale packs until it goes on minus then I will happily do so lol

Oh but I'm also thinking having it on 0 would not allow me to use anymore packs anyway. It will make it harder to gain positive again if it goes negative but I reckon it wouldn't.

Yeah its a good question, but as you are on 0 anyway you probably wont care much about morale lol
