this is getting Ridiculous

[Vahlnir]

I find it hard to believe a group of 8 people aren't getting full credit. It doesn't matter if it's reset, you still have plenty of time to attack it for full. This is only a problem if you aren't in a group.

Pretty much this. There's something terribly wrong if a full party can see it and attack it and NOT get full credit. You also didn't specify how many friends were with you so that would certainly be a factor if it was any less. There could have also been THAT many people swarming the thing, but even still that's odd with the HP boost to A ranks. Sorry about your luck, regardless OP.
