Connecting to a server through Newserv proxy crashes if the remote server has Plus/Ep3 Memory Patches enabled

[Star-X555]

Describe the bug
Connecting to a server through newserv's proxy functionality will fail (i.e. frozen at "quest" download) if the server connected to through proxy has PSO Plus/Ep3 patching enabled. I expect the connection to work fine, rather than crash.

To reproduce

1. Set up a newserv instance with a GC proxy entry, like ragol.org:9501
2. Connect to it through your newserv instance using PSO Plus or Episode 3
3. Crash!

Game version(s) (choose one or more of the following):
Pretty sure this only affects PSO GC Plus and Episode 3, as other versions either don't have the PSO Plus workaround required for memory patches, or don't have memory patches period.

Server log output
As it's not my server that's buggy, I can't really confirm what the errors are. You'd have to ask Matt (ragol.org admin).
