I have similar problem - ingame XVM is working fine, but after few battles it does not work. I didnt use the anonymizer, but I think that it is caused by windows sleep mode - always it happend after I have swap into desktop and go away, after 15 mins windows fall to sleep mode and then inagame XVM does not work. After game restart is OK. I wanted to attach Aslains_WoT_Logs.zip but Aslains_WoT_Logs_Archiver does not create anything....
