No custom assets showing up when launching

[Warclak]

Here's the problem: I download a custom asset or, in some cases, a custom map, doesn't matter which one, this happens to all of them. I set a unit to have that asset and place them in WC editor and they are there(or if downloading a whole map, I see the unit with the asset in the editor). I then launch the map and BOOM all the custom asset units are either A. entirely gone, unable to be seen or interacted with or B. Defaulting to an old asset. For example, I wanted to play the lovely custom campaign Exodus and it looks great in world edit, but when I launch it, the hero is randomly a Paladin and the Spearmen are totally missing. The hero has a new name, with a paladin asset, and paladin hero powers. I tried replacing the spearmen assets but now they just say they are footmen. Everything always looks totally good in world edit but the campaign is unplayable since every time I launch, half the units have the wrong stats or totally don't exist. This isn't the only time I've had problem, even units with original assets listed as custom in Reforged(like Mud Golems for some reason) just don't show up unless I manually reset them to the old Mud Golem asset.
