Just read the patch notes (still no load screen fix) that you need to have all your own Keeps to ente IC.What happens when you are in IC and one of your Keeps are captured?
Do you Get kicked from IC, Do you respawn outside if killed. ?
One of them said something about this the other day, from what i understand it's not an issue they can fix all in one go so what they're having to do is to add minor tweaks and fixes to each patch until they get it right, because the tweaks are so small they obviously won't seem to make much of a difference individually so they're not putting them in the notes because if they put something about it in the notes they would get constant complaints that their fix didn't work.
