Update:
A our team has a meeting 13th september in which we are going to show some of our project, so we are going to focus on that first. After that we will work on other packs also before releasing them together. (I got the suggestion of electrical circuiting/metal packs, and a stone pack)
We will post more updates after 13th september, maybe before if we can spare the time to work on it
