Bots are blamed for this, its not that they caused this. Shitty programming and ncwest not maintaining their game in any form or fashion caused this. The amount of people, bot or not, in contaminated underground at one time cannot cause the instability. The bots are using the instance the same amount every day but the crash happened near the end of the week which means something like a memory leak. Aka shitty programming. They could have banned the obvious bots or god forbid fixed their programming however they took the easy route like every other time and shit all over the few remaining players left. NCWest does not care, they never have. Whatever solution is the least amount of work for them is the solution they choose.
Not to mention this would have happened with a healthy population and no bots. And their solution would have been the same.
