I'd be lying if I said I knew where to begin looking for the answer to this problem.

Anyone able to help? It only does this on a world I've been playing on, and I'm not sure why.

Making a new world doesn't cause issues, trying to play the same world again causes the crash.

LatCoreMC's player data file (latmod/LMPlayers.dat in your save) contains an invalid UUID string.

 

If you care about this data, either restore it from a backup or open it in an NBT editor (e.g. NBTExplorer), find the UUID string mentioned in the crash report and edit it to the correct format (i.e. add dashes so it matches 

xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

).

 

If you don't care about this data, just delete the file.

Post the full crash report, including the LatCoreMC version.

 

It looks like older versions of LatCoreMC save the data in LatCoreMC.dat instead of latmod/LMPlayers.dat.

I looked at the code again and this error is definitely being thrown while reading data from <save_dir>/latmod/LMPlayers.dat. Are you absolutely sure that the file doesn't exist?

 

Side note: LatCoreMC appears to be have been replaced by FTB Utilities. You may want to consider updating.

When I opened the folder, it was empty. There was nothing in LatMod

Update: I also have FTB Utilities installed. If I had to guess, this is a compatibility issue? If so which should I keep?

 

Final Update: After uninstalling LatMod and LatBlocks, the crashes have ceased. I suppose the mod is imperfect and needs more refinement before I can use it, or the mod pack I've built is incompatible with it. Regardless, I thank you for helping me Choon, you saved a world I've invested hours into. :)

Remove LatCoreMC and keep FTB Utilities, since the latter is the replacement of the former.

      Forge 1.21 – How can I add a custom HUD Overlay (Item Icon + Text)

      By OhOhIWontLetUGo · Posted

      Hi everyone, I'm currently developing a Forge 1.21 mod for Minecraft and I want to display a custom HUD overlay for a minigame. My goal: When the game starts, all players should see an item/block icon (from the base game, not a custom texture) plus its name/text in the HUD – similar to how the bossbar overlay works. The HUD should appear centered above the hotbar (or at a similar prominent spot), and update dynamically (icon and name change as the target item changes). What I've tried: I looked at many online tutorials and several GitHub repos (e.g. SeasonHUD, MiniHUD), but most of them use NeoForge or Forge versions <1.20 that provide the IGuiOverlay API (e.g. implements IGuiOverlay, RegisterGuiOverlaysEvent). In Forge 1.21, it seems that neither IGuiOverlay nor RegisterGuiOverlaysEvent exist anymore – at least, I can't import them and they are missing from the docs and code completion. I tried using RenderLevelStageEvent as a workaround but it is probably not intended for custom HUDs. I am not using NeoForge, and switching the project to NeoForge is currently not an option for me. I tried to look at the original minecraft source code to see how elements like hearts, hotbar etc are drawn on the screen but I am too new to Minecraft modding to understand. What I'm looking for: What is the correct way to add a custom HUD element (icon + text) in Forge 1.21, given that the previous overlay API is missing? Is there a new recommended event, callback, or method in Forge 1.21 for custom HUD overlays, or is everyone just using a workaround? Is there a minimal open-source example repo for Forge 1.21 that demonstrates a working HUD overlay without relying on NeoForge or deprecated Forge APIs? My ideal solution: Centered HUD element with an in-game item/block icon (from the base game's assets, e.g. a diamond or any ItemStack / Item) and its name as text, with a transparent background rectangle. It should be visible to the players when the mini game is running. Easy to update the item (e.g. static variable or other method), so it can change dynamically during the game. Any help, code snippets, or up-to-date references would be really appreciated! If this is simply not possible right now in Forge 1.21, it would also help to know that for sure. Thank you very much in advance!

      [Help] How to update a mod from 1.19.2 to 1.20.1

      By Ugdhar · Posted

      The simple answer is there is not an easy way. You would need to know how to program in Java, as well as at least some familiarity with how Forge works so you could port the differences. You would also need the sourcecode for the original mod, and permission from the author to modify it, if they did not use some sort of open source license. So it's not impossible, but it would take some effort, but doing so would open up a whole new world of possibilities for you!

      Crash the server

      By Ugdhar · Posted

      Does it still crash if you remove holdmyitems? Looks like that mod doesn't work on a server as far as I can tell from the error.
