I do. I always know. I always know that any time a PC game gets patched things are going to be abnormal for a period of time that may be short or long. I always know that at patch time you should watch the forums for anguished cries and that the number of complaints is directly proportional to the time it will take to apply hotfixes.
I know this because I've been here too many times before and I've somehow managed to learn from the experience. Why other people don't do the same I'll never know, but it's fun to laugh at them so hey.
My personal expectation at this stage is to have on average one hour of extra downtime per day for the next 3- 4 weeks and I'm planning accordingly. I might be wrong about that, but I'm confident that any error in that estimate will prove to be an overestimation rather than an underestimation. As a result, you won't be seeing me in here crying because I expected things to run smoothly when they didn't.
That's a rudimentary survival skill for PC gamers; anybody who's been playing PC games for 6 months or longer really ought to have that worked out by now and the ones who don't... well, like I said good chuckles are good.
