Shadow PROBLEMS! + Sneak Peek Image - Unlocked Blue Gum (Patreon)

Blue Gum
Another unlocked tree on the first image, the Blue Gum (Eucalyptus).
I worked on additional recolors, but found a problem with not only this tree, but also the other trees and plants I was working on and made additional recolors for.

Flowering Shrub
I didn't noticed it before, but on my image of the unlocked Flowering Shrub, you can see that the shadows of the plant don't look the way they should. You can't see a shadow for each individual leaf, which is normally the case. Instead the entire polygon has a shadow. This problem only occurs after adding new swatches unfortunately.

This same problem I also had with the Blue Gum when trying to add another recolor of this tree with green leaves. As the shadow of this enormous tree is much bigger, I immediately noticed. I then checked another tree I was working on and found the same kind of problem.

Strange enough, the birch for which I made a white bark, is not having this problem and I have not a single clue why. 

Discord Help
Luckily there are modders with more knowledge about these things, so I'm now trying to find help on Discord.

Hopefully fixing this problem isn't that big of a deal as I was already thinking about placing the Tree Pack in early access. Now these shadows don't work, I will wait a bit longer as I don't like to share objects with bugged shadows as in mine opinion they look very bad.
