The affected code was ported from H'uru where NetVaultNode has a zeroing
constructor. OU does not have a zeroing constructor for this class, and
instead assumes that all allocations will be done with NEWZERO (there is
a debug mode assertion to this effect). The result of the improper
allocation is that the node fields flag could be garbage, causing a
vault node with random contents to be written to the server.
Unfortunately, NetVaultNode::Read_LCS is not extremely resilient to
reading in unexpected data, so this may result in a crash.
Some of the Python code expects for explicit Age initialization to
complete immediately. Rewriting that would be something of a chore, so
this will prevent first time clicks on the Er'cana and Ahnoying
Cathedral books from causing a perma-stick.
