I see you can only open multiple Buccaneer's Bounty chests up until you go above 100 FPs. I guess it makes sense, but it still makes opening a lot really slow, which I assume was the idea behind allowing multiple to be opened at the same time.
I think allowing this one feature to break the max 100 FPs rule would be better. Now that you can add custom amounts to GBs I don't see how this is such a big deal. A full year's worth of bounties is only 3k FPs, which isn't really that much. Many players regularly get more than 1k FPs from collection and/or GBG, so I don't see how a one-off, big boost of FPs in your bar is such a big deal. You would still have to spend them before you can collect more FP buildings, so I don't see the big difference between spending 3k from FP packs and this one-off 3k from FP bar.
