Hello,
i just want to report this, guildies noticed the same.
Whenever the team instance starts (which is buggy by default, dc's, etc etc), if i change the tab in the browser, the game automatically dc's.
It's not some random dc, because i run the game for 8h while on work, never getting a single dc, except when the team instance is.
Can you check the connection with TI and Tabs (Chrome and Firefox had the same problem, haven't tried Opera/Edge yet) ?
Thanks
Regards,
K
