[General] 1.31 AI Hero Fix

[Ravager16829]

There is a bad bug on 1.31, where AI heroes don't use their spells correctly during the melee games. Not sure if regular units also have the same problem. Apparently, there's a workaround for that bug by resorting to triggers (or scripts, or something like that). So not sure what it does. Tried searching Hive for answers, found this thread, but I need an alternative one compared to that trick as of today. Was wondering if anyone could explain what it does.

Also, I heard that someone has posted a custom script (common.ai) which has AI hero learning spells being fixed, but it was too old (2019), and the download is now broken.
