CBP1 Maps consistently crashing my server

[Clint Goudie-Nice]

Found the bug. Interestingly when a friend of mine ran it on his server,
he encountered the same crash, but the stack contained more information
about what was being executed pointing to something I was running. The
bug was where the parent class of a subclass wasn't required to be on
the client while the subclass was. Looks like it hozed the replication
and killed the server. IE:

 +------+
 |Weapon|
 +------+
    ^
    |
+-------+
|Missing|
| Parent|
+-------+
    ^
    |
+--------+
|subclass|
+--------+

So, CBP1 appears safe, and also fun. Go pull it down.

Greetings all, I noticed that there was a re-release of the CBP1 for
UT2004 and installed it on my server. Consistently while we're playing
these maps, we get the following... 

This sample was with CTF-CBP1-Betrayal

Here's another sample from BR-CBP1-BreakLimit2004

Any ideas what might be going on here, or how I can work around this
crash?

In case it's a mutator I'm running that doesn't show up here, What does
GetClassNetCache even do?
