Forge: 1.15.2-31.2.44
Xercamod version: 1.15.2-2.6

A weird little compatibility issue. When Xercamod is installed alongside both Quark and JEI, JEI doesn't work. JEI shows up with every other mod, but when Quark is installed, for some reason it decides, "Nah I ain't doing that holmes."

Quark version: r2.1-245
JEI version: 1.15.2-0.10.1.77
