Hello I have created a mod and published onto steam, and after a few days, I receive a commend that supports the modding idea, but I do not know how to update the changes. Do I have to collapse the active mod and post/publish as a new one? Or I could upgrade the mod I published in some other way? Please help Looking forward to replying.
No - just reupload the same mod with the changes. The modinfo file tells steam the SteamID# of the mod - so it knows which mod to update. So as long as you don't change the number in the Mod info file ( which is automatically added on the first upload ) you should be fine.
