There were over 65k in attendance.
Weather and capacity are not linked.
Capacity is the number of people you can fit in a stadium. Weather is the state of the atmosphere at a place and time in regards heat, dryness, sunshine… etc.
Weather changes. Capacity doesn’t.
Therefore, if weather is the only (or primary) reason why the Bills can put 90k butts in seats in September, but not December, then it doesn’t make sense to reduce capacity. What makes sense it to mitigate the weather by adding a roof.
