Multiple FB attacks against same base within minutes

soixie, this is not about def, it is about fb doing a lot more attacks than expected, in my case in 1 wave with only 3 bases, they all attacked at a higher frequency than normal. In 2 wave area you can expect attacks around every 2 hours, in 1 wave with only 3 fb, 1 attack +/- 6 hours - 12 hours
