today, the Winter “8-bit” Mode was started on Russian server. According to numerous reports, this mode heavily interferes with many mods, including XVM, causing the game to crash. It’s possible that the mods will be fixed on time for EU release, but if they are not, be aware that they are the cause of your client not working properly.
To talk specifically, the problematic file seems to be Application.swf in res_mods/0.9.5/gui/flash folder. And here are a few screenies from Russian server.
