Maximum concurrent IFarmer attacks

[JayanWarden]

Hi,

Is there a (customizable) Limit for how many concurrent attacks the IFarmer does?

I have troups sitting around at idle and more than enough targets for the IFarmer to farm.
I have seen about 5-6 concurrent attacks, ignoring returns.

At the moment there are 5 attacks and 9 returns.
I have enough troops for 4 more attacks, but the IFarmer does not send out any more attacks.

Is there a setting that I am not seeing?

Sincerely
