That isn't true. Modders ignored most of the last version and just added a couple of things they liked to their version, which is based on the old vanilla game.
And what is wrong here? In fact, there are 2 different games. The author's version contains one content, the mod version is different.
1. The author's 0.979f
2. The version with the mod 0.978e
If you look carefully, the new stable author's version was came out only on July 15 and then with a question (Probably ok?)
The authors of the mod version took as a basis the working version 0.978e.
That they should update each version, even if the author himself is not sure that this is a stable version?
What was missing - a bunch of versions with bugs?
And compare how much content the author added, and authors of mods. And how much money does the author and mod authors get for this?
If you are not satisfied, try to do it yourself, or help with money, and then you will criticize.
Mods authors generally do not have to update anything to anyone
