I'm missing a significant number of battle points. I had nearly 300 and the next thing I know I'm down to about 25. I don't think you lose those if you lose battles (you just lose pirate rank points), but even if you do, I was not attacked enough to lose about 250 points. Anyone else lose battle points recently?
Perhaps you bought something from the shop that has a BP cost associated with it, or did some training in the Academy
Ahh...That's probably it. I didn't realize those points were actually subtracted. I just thought they were a threshold requirement. I built the Academy which is 75 BP's and I've done a few upgrades. I don't see where the upgrades say how many BP's they cost. What things cost BP's to upgrade?
