I think FCounter is used to calculate the intervals at which bombs are created...not too sure. It's used in the Delphix samples.

Anyway, I set FCounter to 0 in the attacker.create and the bomb.create and now it generates bombs for about double the time it used to do and then it stops for some reason.

I now changed the values to 600 and 300 and it seems to be working fine :-)
