I'm having a lot of fun with this mod, but I noticed that there a lot of units that work fine in custom battles that aren't acquirable in the campaign. For example: Mounted Hyrulean Knights, Triforce Guardians, Bronze/Iron Knuckles, Repeater Crossbows.
Is this intended? Looking at the EDB, some seem like they might be bugs, but Iron Knuckles aren't in the EDB at all so it makes me wonder if these units just aren't supposed to be in the campaign yet.
If I play a new campaign I'll probably edit them in myself
