i fixed it. it was because of the version of nw was incompatable. now i have a new problem related to DLC. if the user doesnt have DLC installed it will crash saying reference error. falsevariable is not defined
How are you. Don't worry, I'm glad you were able to fix it!
I want to tell you that I am currently researching and using in my game an additional plugin that came out very recently:
I leave you his Itchio in case you want to take a look:

Mainly it fixes the Achievements system that for some reason SteamLink was not working, and adds other additional features.
I recommend that you review it and try to see what you think.
