Well, 4 month without any news it's a bit worrying xD There are only problem posts and, although Restart said that this started as an open project, no one skilled is really participating in its improvement. It's a shame....
But so far I didn't discover what would be the best way to fix this. I guess the best way in this case would be to compare relevant core script areas beween MV and MZ, because there is zero documentation I could find about those areas of code
