Do you get it if you don’t collect the second-to-last rewards by itself? I remember testing it out very early on:
- I did enough battles for 18 stages of rewards and collected them.
- I did enough battles for the 19th and 20th rewards, and collected them together.
I only got 1000 extra VP instead of 2000 VP. I only tested it once, and haven’t tried again since then. I’ve been collecting the 19th reward on its own first.
