The version that Minehut is on is b1692, while the latest build on the Jenkins page for Citizens2 is b1704. Since Minehut switched to PaperSpigot, Citizens2 has stopped working. Updating to this version may fix it, as Citizens2 for 1.14.2 is in beta. https://ci.citizensnpcs.co/job/Citizens2/lastSuccessfulBuild/artifact/dist/target/Citizens-2.0.25-b1704.jar
