Aternos has recently added the mod Superheros Unlimited as an option to load onto servers. The problem? Aternos does not have the dependency mod.
Superheroes unlimited needs the legends core mod in order to launch, but when I requested it, Aternos refused to add the legends core mod. Why would you install a mod which needs a dependency, but then refuse to install the dependency? And, no, this legends mod is not the right dependancy for superheroes unlimited. It's not even the same minecraft version as superheroes unlimited!
Aternos Team, for our sake, just add the right dependency mod. See this as feedback, not a mod request.
Sincerely, SilverSkele.
