Hi there! Thanks for the detailed explanation!
1) I would love to make a compatibility for this. Because I really like this plugin. But the Collision plugin is probably very complex and big. I would need a bit of time and effort to get what is wrong. And I don't have that time now... =/
2) Can you send me a project replicating the issue? Send it to my discord: hakuenstudio that I will take a look into this!
