Not sure exactly when, but I noticed an error message during load time, (and it took a few times to figure out what it was during the rapid console scroll,) and it seems that the Sandbox plugin was deleted somehow and the launcher is not repairing/replacing the files.
Is there any way to force Windower to redownload it or to download it separately/stand-alone? I'm getting input/chatlog bleed again and it is annoying.
