I am trying to merge my survival server with my normal server(creative). The main thing in my way is that the creative server runs 1.13.2, while my survival runs 1.14.4. My chaotic attempt: replacing the 1.13.2 bukkit.jar with the 1.14.4 one. Result: Chaos. I got a huge repetitive error, and don't know that to fix or do. I would greatly appreciate any help. The log is in "Oof.txt." Plugins Installed: ChatEx PermissionsEx 1.23.4 OpenInv Multiverse-Core 4.1.0 WorldEdit 7.0.0 WorldGuard 7.0.0 Some plugin(s) may be outdated, but they still seem to work.
