For me, even after clearing the configs, Shrines' mixins seem to conflict with Unearthed's mixins.

Looks like this was caused by an build issue/project miss configuration on my side. I didn't try to reproduce your issue, because it seems like the Mixins in my mod were broken and the problem wasn't caused by incompatibility. Could you try again with beta 9 and give me a feedback whether it works now?

Indeed it works now. Thanks for fixing!
