Weird stuff happening right before crash

[xhuggels]

So ive noticed something at least with my games. There is a trend to the happenings before a crash. The game mechanics go wierd...for instance my latest crash. I was just sitting in my base minding my own business. Then a trade caravan comes and walks around my base and im thinking, yay, if only i have a shop counter this might actually work, they are coming. Then suddenly out of nowhere they attack me, and right after that two groups of slavers join in as well.
So right about now im thinking, this is odd, my relations with both of them are perfectly find at 0, why would either one of them attack me, much less both of them combined, with the trade caravan leading the charge. And then i start thinking that odd things to happen from time to time, and is always followed by the void making an appearance, and sure enough there goes to of my guys into the void at the moment they regain consciousness...and right after that comes the crash.

So ive noticed something about the void. It happens most at the exact moment a character changes in any way, whether it is getting in or out of bed, regaining consciousness, changing jobs...getting loaded and ive seen it happen when the time gets slowed or sped up. They disappear from time to time when you switch between two characters far apart on the map too. Any change basically, and it is safe to say a crash follows this.
What im wondering though is whether anyone else has noticed weird little things happening a few minutes before the void makes its appearance? Is it just a gradual degradation of sense until BOOM!
