The addon is not working at all. When I try to go into the options, it says Failed to load Z-Perl Options (MISSING).

I have the same issue. All Z-Perl Modules are missing but one!

EDIT: As a workaround if downgraded to 7.2.5 for now.

EDIT 2: Downloading Z-Perl directly from GitHub gives you all the Files for 7.2.6. So it an issue with missing Files on the CurseForge side of things. Still can't use custom Spells for Range detection but the rest kind of works.

I manually pushed a new version to curse, their packager seems to have some issues,

How do you download from Github?

You are officially my new hero. It's working again. Thank you.
