Help with dependency warning

Hi, I'm making a custom template for a roleplaying game. Created it as a copy of magic and started renaming/tweaking until it got working

But even then, I'm getting a strange warning that says:

The package 'exalted' uses files from the package 'exalted-blends.mse-include', but it does not list a dependency.

To resolve this, add:

depends on: exalted-blends.mse-include 2019-12-03

I searched in all the files in /data folder and found that the file that is using that package is the "script" in my .mse-game (At line 185):

# needed by all style files anyway

include file: /exalted-blends.mse-include/new-blends
But if I try to add that line (Just before the include or at the start of the file), MSE goes crazy, throwing a bunch of errors (About a lot of variables not set) and, in the end, showing:

Warnings while reading file:
...\MSE\data\exalted.mse-game/game

On line 11: In include file 'script'
On line 3: Expected 'end of input' instead of 'on'

I'm under the impression that adding that dependency in that file causes it to fall apart, since it doesn't recognize the "depends on" command. But why then does it ask me to add it? I don't understand :S

Has anyone faced some scenario like this?

Thanks for your time.
