Can confirm this issue too, problems in phase 3 and 4 with the game becoming unplayable after 7pm every night...Problem resolves itself around midnight. Im with EE, and i contacted them who said they'd pass info on to the relevant team. Guess nothing is being done. As of now, game is unplayable, takes 5 mins or so for an npc to respond to a click, 5 mins for an ability to fire off etc.
