Mass flight bug - wrong script processing

This is what I found there (extracts):

The spell is punished for excessive fatigue! And thus Arrow Fend was definitely a better choice...

Actually, Arrow Fend got score of almost 180 000, while Mass Flight's total was 150 and even before fatigue reduction Mass Flight's score was under 1000... So there's something else going on in there. Perhaps Arrow Fend's score increases for every one of your units but Mass Flight's doesn't (i.e. Mass Flight isn't considered a buff, which someone already suggested), or perhaps every enemy archer on the field increases the chance of casting Arrow Fend, or perhaps castle's towers are considered more heavily than they should, but fatigue reduction wasn't relevant in this case.
