Simple solution just hex out the cvar "Reconnect" and it will stop this action. Use a hex editor and search for the cvar. It should be in your MOHAA.exe or gamex86.dll

   

   

   

   EDIT:

   and this also will not corrupt your reconnect cvar it will just change the text. If u want to reconnect than make sure u know what u hex it to for example a good idea is to just hex one o to a 0 so it looks like "Rec0nnect"
