Hi there!
This kind of plugin is usually too complex. Best way for me to debug this is if you build a sample project for me, with the ARPG plugin already configured and ready to replicate the error
I mean, in a way that I open the project, hit play test and manage to replicate the error easily.
If you have any paid plugins on that project, send me the project through discord:
hakuenstudio
Otherwise, you can send the link here.
