I previously posted this as a different issue, but after further investigation, I have discovered that the only blocks I could find allowing rocks to spawn on ice are those of Ecologics thin ice (ecologics:thin_ice). Could we possibly get mod compatibility with Ecologics or should I explore other means of resolving this issue? Look forward to hearing from you ^_^
