So I was using my year two insurmountable skullfort, and found that it works just fine with both the striker and sunbreaker, providing dual belle charges on separate melee activations, although when switched to defender, one kill would consume both melee charges. Even with one on standby, and another charging, upon kill, a charge would be used, and the other would restart its charging process. So is this meant to be? Or is it a bug undergoing a fix.
