Ninja mod not working

Thank you very much for these information.

I can work with that.
The launcher uses a version from 2018 and points to this topic in the forum.

Unless I’m mistaken, this mod was made with lua in mind (the support for that was dropped a “long” time ago), but might be able to work if all the parts are removed that try to access lua.
All the other errors you’ve posted screenshots of should not prevent the game from loading, aside from the last one.
I’ll test it as soon as I get the time for it.
