Compatibility issue, doesn't work with Requiem. Simple enough. It's been a while so I don't remember the details, but it hard crashes on startup without giving much of a reason why.
Used to work fine, however. But a requiem update completely broke the two working together.

I guess comparing requiem's pre update code with the current patch to see what could've caused it? Might be a requiem problem but they aren't quite responding to issues

I think the latest version is still incompatible with Requiem

Reopen if this still happens on the latest version.
