Not sure about all the posts - but I have not bought anything in this game and I will have received all the rewards, including day 6, lvl 45, unless my PC crashes tonight.

Lvl 45 was not easy, but it is possible, if you force yourself to collect EXP nonstop (train) and use your stamina wisely, doing lab runs 2 times a day, and collect exp in the pirates ship at least once a day - that right there can yield you 120k exp, with auto train, when your not online and finishing all the dungeon quests as soon as you can do them, you should all be able to reach lvl 45 by day 6

again it was not easy, so i agree that this was not a beginners type of reward in line with the day 5 and day 7 rewards, because you will not get day 6 unless you have already beaten the plague professor - early on

honestly day 6 should have been reach level 42 or lvl 44 , day 4 should have been like reach lvl 38
