if you spam click the brez button you're gonna port out because you have the "ACCEPT REZ IN 5..220.127.116.11." button and the "RETURN TO MEDCENTER" buttons, and when the timer hits 0, for a second, only the "RETURN TO MEDCENTER " button is in the middle of the rez window, before the "ACCEPT REZ" button reappears, so if you're spam clicking the countdown button, you wind up clicking the graveyard rez. Just need to not spam click, and wait up the actual Accept Rez button appears.
I'm sure they'll fix this in the future.
There are times, even if you wait 2-3 seconds AFTER.. and you click ACCEPT REZ.. It will still kick you out.
