I am running my own server on 1.12.2 with the fossil and archaeology mod 8.0.0, Jurassic craft mod 2.1.21, llibrary 1.7.17 and none of the fossil blocks seem to spawn in my world and i try to spawn in the dinosaurs in my server world and non of them spawn. But when i go to single player everything works perfectly. What is the problem?
