Minecraft Version: Forge 1.12.2- 14.23.5.2803 I'm trying to run an RL Craft server for my friend and I, and we always come to the same screen, saying there is one missing registry: Minecraft:dataserializers. It gives both of us an option to continue, and it works after I hit yes, but when my friend hits yes it takes him back to the main screen. Why is this happening and what can I do to fix this? I haven't found any answers browsing other threads. Here is my latest.log: ArP8EmjM.txt
