Loosing Battle Points

I was at 1500 BP or so, and now I am at about 300 after being plundered.

This happened a few days ago, and the BP magically came back.

At the moment, they are gone, again.

In each instance, the BP disappears/re-appears after a plunder session.

I am using an iPhone.

Is this a bug, or is this normal?

 

Really good question. I came here looking for the same answer as I just noticed my BP has dropped significantly. How/why do we lose BP, @Chris [Midoki]? (or anyone that knows...)

 

Some upgrades and buildings cost BP and is deducted from your current BP.

 

1,000 BP sounds like a Mystic Mortar - 2.6 Mil gold PLUS 1,000 BP. The academy also costs BP to upgrade.

 

OH! I need to pay more attention to what things cost. Thanks!

 

I thought the same thing when my EP dropped after a Lighthouse upgrade. I thought it was only a benchmark number and not deducted as a cost.
