Yep. And even 4 hours before the event should have ended before it was extended. It was closer than the last events but it was doable.

How late is too late for buying a quest slot? Hard to say. When you get very close to the end of the event, luck will also play a role. I calculated that I could get ~1100, maybe 1200 suitcases per day per slot if I play regularly but not excessively. So... if you know how many quest items you need for finishing the event successfully, you could count back to assess if it is too late to buy an extra slot or not.

Say you still need 8000 suitcases, have two full days left and three slots active. You would get 2x 1200 = ~2400 per slot till the end of the event, x3 = 7200. Buying the fourth slot would definitely help in this case and you could even put it off until the beginning of the last day.

If you need 10000 suitcases, have only 2 active slots and 2 days left, it could already be too late (4x 2400 = 9600). If you aren't really lucky or if you don't play 24/7.

I think the best way to be certain about getting all the rewards is to spend gems on the second slot as soon as the event starts and unlock the third and fourth before thinking about anything else. Maths will do the rest for you. :0)
