I don't know why this update was required for servers. If we can't extract maps larger then 64M, then this is indeed a significant problem. Unfortunately a lot of ignorance is present with shipping assets, and since the VPK system is busted by design. This definitely needs to get backed out before the weekend. There's a great deal of CS:S maps that we, along with many other servers, unfortunately host that are over 250M compressed with bz2. Uncompressed they're surpassing 500M, primarily due to the fact assets can't be shipped and mounted via versioned VPKs.
