Pink Bean Jump Quest

IDK what to do with these granadas.

The first time I got one, I thought I could save them up so I left with it and it disappeared.

The second time I got one, I dropped it in front of the box, and it took off one seal, which left four remaining.

This time (the third time), I reached the bonus and was REALLY annoyed to find out that there's 5 seals again. I dropped the granada and it took away one seal, which means there are now four remaining.

How are we supposed to finish the quest if we can't save up the granadas and the seal grows back every day? The quest resets every day too.

The seals aren't meant to grow back. Mine didn't, and currently only has one seal left.
Best for you to do is to try again and see if the problem fixed itself.

Will this quest reappear in the quest log after 24 hours? Or does it reset at a certain time for everyone every day? Considering it's Maple, I'd say the first if either of those. I don't remember what time I finished yesterday, so I don't want to climb all the way to the top to find out that I can't do anything.

@above: No, the quest resets on a new day.

Did you complete the jump quest the 2nd and 3rd times on both the same difficulty? That might be the problem. But I honestly don't know, since I've never beaten Hard yet.
