While the add-on is fully tested before each release, on multiple OS(s), and it was working fine in the last (v1.6.0) tests too, i can't rule out problems for edge cases.
If you are willing to help me make the add-on better for everyone, it would be useful if you could open an issue on the repository with some more details (about your blender version, OS, and eventual error messages you see in blender while having problems), so that i can try to reproduce the issue and work on a fix.
Custom Templates
literally none of this addon's function work. templates can't be read, made absolute, etc.
idk who's passing dysfunctional addons like this, but they need to resign before they recklessly approve any more
