Sabotaging oxygen is kind of a mess right now. Having it chunk out the total oxygen which already drains pretty quick allows personoids to just run around oxygen rushing and crouching into bushes rather than playing methodically. I suggest we revert the oxygen system to the individual and having sabotaged oxygen inflict oxygen drain chunks on the first individual to to use it or perhaps overload their oxygen systems substantially increasing oxygen drain until another player helps them replace/fix it.
