Hello again Oktober!
I may be getting close to a solution, the version i uploaded last could have possibly solved it for you, but if not, you could send me your project, or send me the map that is having the issues, in a project with mz3d setup with your configuration so i can watch the events and make certain that i've tracked down the problem for you.
