I'm not sure you can update a mod just by changing the mod.toml, I'm not sure of all the changes, but I would imagine that the code would need to be changed to match any updates/changes from 1.18.2 -> 1.20.1 You could try sharing the full log (instructions on doing so in the FAQ) and seeing if anyone sees any fixable errors.

Mod is Isle of Berk. I've updated the mod.toml file to match geckolib, but the error in the title keeps showing up upon launching.

The issue has been fixed thanks to TileEntity's help and I'll make sure to read up on the FAQ more before any other help request, thanks lads.

gotcha, I forgot I had done some changes to the mod pack after making the initial post and I believe that is what was causing the issue so after I run this test I'll come back with either a new log following the FAQ or good news.

Always post new logs (to an external site, and posting the link here, as described in the FAQ) after removing mods/trying something to fix it.

forgot to quote so you get the notif or whatever

removing the mod entirely seems to crash the entire game, as just booting it up ends in "an unexpected issue occurred and the game crashed". I'm gonna try some other things but please give me any more ideas because I'm clueless on any of this.

Remove the mod MVS

Make a test without the mod icarus

Okay so i don't really understand this whole logs thing. But my minecraft keeps crashing everytime i turn it on and im not sure what the issue is so if someone could guide me how to fix it that would be awesome https://mclo.gs/aeD8NII

Hello its servers 100% cool servers

Add the crash-report or latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link to it here

Greetings, I was playing my BMC5 V49, 1.20.1 world, and I suddenly got disconnected and put on a error screen with the following message ; Internal Exception io.netty.handler.codec.DecoderException: Failed to decode packet 'clientbound/minecraft:custom_payload' Since then, every time I try to start the world, right after the "loading terrain" step, it goes into "Saving World" then crashes... I have spent many hours on this hardcore world and I really want to get it back... I pray for someone's help. Thanks in advance for your time. Sincerly yours. Julien

Yoo kinda messed up how he just left, but I am having the same problem, not my server but a server

I installed the previous release version and everything worked, thank you!

There is an issue with the mod cold_sweat - remove it or try other builds

https://mclo.gs/i6XHHiW

The link is not working - use https://mclo.gs/

Today I found my old modpack and when I tried to start the game it crashes in the Logs I found that the reason for the crash is the "Cold Sweat" mod when I disable it the modpack starts, I tried changing the mod versions but it didn't help I'm playing on version 1.16.5 and here is the link to the crash Logs https://pastee.dev/p/s7KNLxKa Does anyone know what the problem is?

Hi, do you still need help ?

Very good summary, and quite accurate: the difference between a good mod and an excellent mod often lies in the invisible quality rather than the content.

Neoforge is not supported here, I would start by looking at https://neoforged.net/ for support

It's a fairly large modpack and it was crashing on trying to create a world before but now it is crashing on the initial loading screen. Here's the crash log: https://mclo.gs/Rqp6qQx
