I migrated my game to Jumpgate. First day worked like a dream: no issues. Second session was a nightmare. One of the players could not get into the Jumpgate game and got in the Legacy Backup instead: it took a while till we realized what was going on. He tried many times but there was no way he could get into the Jumpgate session. I tried to delete the account and add him again into the game, to no avail. Then I ended up opening simultaneously both Jumpgate and Legacy backup in the same browser / different Windows so as to share content. This was not working well as from time to time my Jumpgate game was suddenly converted to the legacy (probably the system did not like having the 2 sessions open simultaneously). Let's see how I fix this access issue tomorrow.
