Weird List out of bounds exception

[Nathan Sutcliffe]

I've been chasing an elusive bug for quite some time and I'm running out of
ideas. There's one error that's showing up again and again in the client's
error log that I don't understand. The stack trace is later on in the
message.

(The client is using an application compiled with the 2.11 code, but with
the 2.12 server. They connect over a very flaky WAN.)

It seems to be happening when I call Table.Open. Why would there be a list
out of bounds error here? Has anyone seen anything like this? Any ideas at
all would be appreciated!

TpsTicketMgr.ProcessIncomingTicketsTimer: List index out of bounds (0).
