Coming home late I set off to do my quests. I've just gotten this event: Your Bonus Quest CSC Credits buff has worn out!

I've taken to activate my Morty Cards even if I only have 1 to 4 quests left, picking up where I'd left the next day. Because I got tired of putting them in my vault and fiddling them out again the next day.

We were never told, the buff expires, were we?

I had the same misconception before. If you click on the icon for the buff you go to the buff page where it tells you how much time is left. If I recall it lasts 24 hours.

@ BoaConstrictor As said, the Morty Card buff expires either after 24 hours, or after you do 5 quests.

So if you activate one at 3pm Subeta time, but you don't do 5 quests, it will last until 3pm Subeta time tomorrow.

This is sad. And we should have been told.
