I don't see any reference to that error in the current codebase, so I am guessing EP fixed it in his last build.
Give my latest build a try:
https://www.dropbox.com/sh/hsznyxpsatyi ... FpXwYOoGJaI'm calling it 2.06 to differentiate it from EP's 2.05 build.
I completely re-vamped the Telnet routines, so you should get a stable reconnect even if you are running the public/unpatched version of Mombot. StarKiller and I ran this build for the full duration of HHT without any problems.
This is not a full release, so you will need to drop this into your existing TWXPROXY folder. Delete TWXSetup.dat and your data folder.
The source for this build is on Github:
