Hi guys, after checking your post, it reminded that a previous freeze from the start of the war within.
If you go to your guild “info” tab, and click on “Click to set news filters”, there’s a lot of checked boxes.
if you uncheck them, it fixed my freeezes each time i was loading a new instances.
I previosuly unchecked them all, but it seems Blizzard re-enabled them automaticly with a server/game update.
Hope it will help ! Cheers !
