[General] Triggers from Latest to Old Patch

[TheFireMage]

When I convert a GUI trigger to custom text, it seems like I can transfer GUI function that does not exist in old patch into it. But that's what I did with one category without any error, When I copy the entire triggers and units. It appears error "Function does not exist in database: BlzSetUnitBaseDamage" but still proceeds to open the map which in turn the map becomes unplayable unless run by the same or newer patch. This did not happen when I just copied and converted some of the triggers. I looked through my triggers and the triggers I copied are the only triggers that have function I mentioned above. Can anybody explain why? I thank you in advance.

Functions that start with the "Blz" prefix only started appearing in patch 1.29 so if you try to use them in older versions they won't work at all.

What if I use WEX?
