Ok, while I still think you're not on the right track with a lot of this discussion and since it's already posted here... the actual error as to why it doesn't show turrets is as follows:

if (a.def_ally_losses.m_j > 0) {
                b += wrap_n_item(addCommas(a.def_ally_losses.m_tu) + " Turrets")
            }

Notice that we are looking at jets and not turrets for the test in the if. It's coded really poorly, but that's the whole problem right there. Changing m_j to m_tu in the check will resolve the problem. I've got a branch going with some changes for this file, I'll throw this in too.

Thanks!
