On steam in the Pinned Post for Official Links, you have a link that points to the Official page on Github for Modding. This leads me to think that Modding is Officially supported, but on the link you provide to Github, in the Readme, it appears that Modding is not supported.
Please Clarify. In the pinned post on steam, please add a comment to the link as to whether Modding is supported currently or not. You seem to encourage modding in some places and discouraging in others. Please respond on the Steam forums and Clarify this issue. Or maybe create a Pinned post in the Modding sub forum that explains everything and what you are planning about Modding in the future.
Also, the Issues that have been reported there, and many here have been ignored. Why even have this here if you are no longer even looking at these issues. If you no longer desire to respond to these issues here, Please, just delete everything here. And let us know in the Pinned Posts on the Steam Forum or maybe elsewhere, what is happening. And Please No Discord. Many, if not most of us prefer not to use Discord.
