Sorry, but I would like to ask if anyone else is experiencing the problem: java.lang.ClassCastException: class net.minecraft.client.player.LocalPlayer cannot be cast to class net.minecraft.server.level.ServerPlayer (net.minecraft.client .player.LocalPlayer and net.minecraft.server.level.ServerPlayer are in module [email protected] of loader 'TRANSFORMER' @19a64eae) This problem appeared yesterday, while I was testing parts of my mod, which I had previously tested. I thought I might have messed up somewhere, so today I went back to a previous version, already tested and functional, and it turns out that I ran into the same problem. Someone knows what is due? I can't share the entire code, but I can give you the parts that cause the error, I hope you can help me. Thanks in advance. DataUtil Class public static void setBooleanOnServerAndSync(Player p, String key, boolean value, boolean temporary) { p.getCapability(PlayerDataProvider.PLAYER_DATA, null).ifPresent(playerData -> { playerData.setBoolean(key, value, temporary); Messages.sendToPlayer(SyncPlayerDataPacket.toClient(key).setBoolean(value), (ServerPlayer) p); //It fails here if (value) { ResearchUtil.markResearchAsUpdated(p, key); } }); } Gui that calls the previous method public void tick() { this.timePassed++; if (this.timePassed > 1000) { this.minecraft.setScreen(null); assert minecraft.level != null; assert minecraft.player != null; DataUtil.setBooleanOnServerAndSync(Objects.requireNonNull(minecraft.level.getPlayerByUUID(minecraft.player.getUUID())),"eldritchDream", true,false); } else if (this.timePassed == 20) { Minecraft.getInstance().player.playSound(Registration.DREAM_ALIENIS.get(), 1, 1); } super.tick(); } Error Log (Website paste.ee)

When I create a new world, after having configured the new biome using Citadel's ExpandedBiomes, it is not generated. I have decided to take the map code from Alex Caves, just for testing purposes, then I will delete it. This map can't find it either. But, in locate the biome appears, even if it cannot be found and when generating a world with a single biome, I can choose the biome and it "generates" it. I don't know where I could have made a mistake. Github repository Any help is welcome. Thank you all in advance, for helping or taking the time to read.
