Bottom line bud, my original post was about the other guy presenting his speculations as a "Fact", causing others to repeat it like it was actual "News".Again, not saying you're wrong. In fact, you're probably right. I just checked his digibang patreon and is active with some previews from the next update, published last December. Having said this, I still think some characters and icons are very similar to Digibang's, whom has a particular style, not your typical daz model. However, this other dev could be inspired by Digibang, just as Melissa's model from Foot of the mountains.
Personally I'm not really interested in speculating about this stuff. I've already stated my opinion and don't have anything extra to add.
Other than I wish people would clearly represent their speculation honestly.
