Look at it this way: Nearly every serious problem with SR5 Core came from a rushjob.
Curious as to what you mean by this?
There are a few instances that if you go and and look at SR4a, the text is copied over, instead of re-written for SR5.. so, it causes confusion, because the rules have changed, so reference to old rules throws a wrench in the works. This may be laziness and not just a rush, but more time spent should have found these.... and no, I don't recall each exact one, but the forums are seeded will with the instances.
My biggest problem is with the printing.. The pages aren't bundled into 32 page fold bundles and glued in groups, each page is glued individually it seems to the spine, and that is why pages seem to be falling out. Granted, this is the Printer, and not CGL, but still. Some of the other books on the market around this size.. Pathfnder, and Star Wars Edge of the Empire.. if you look along the spine, the Glue wad is a lot thicker, and the pages are folded and connected in smaller bundles, and each bundle glued into the spine, making them a lot more durable and resistant to pages falling out.
This is probably a rush job issue as well. If they were willing to have the books even later than they were, they probably could have had few test books shipped, examined, and found the shoddy binding job, and sent them back for a better binding job... Just like they probably could have waited on the 2nd printing until the Errata was out, but first printing sold out before street date because demand was so high.. so, another rush job to try to get Shadowrun into as many hands as possible
I say probably, because these are my best educated guesses
