Forge crashes during startup for any 1.20.1 modpack

1.20.1

Posted November 26, 2024Nov 26

I can't start any Forge modpack for 1.20.1. It crashes with exit code 1 before even getting to the title screen.

I've even tried creating a blank 1.20.1 curseforge profile with Forge 47.3.0 and no mods, but that crashes as well. Here's the log file from that: https://pastebin.com/Gtk3E0gC

Here's a list of things I tried before posting here:

fresh reinstall of Minecraft
updating my Intel drivers
updating my NVIDIA drivers
reinstalling java runtime environment from java.com
installing the JDK 21 from oracle.com
installing the JDK from adoptium.net

Nothing changed.
BUT: This ONLY happens for 1.20.1. all of my modpacks for 1.19. All of my modpacks for 1.19 and below start just fine.

FTBQuests quests not showing in server

Most likely, this is no longer relevant for you, but I will still leave my answer, because I had the same problem, and I did not find a clear answer anywhere. To ensure your server players have the quests you created, all you need to do is transfer the necessary files to the server. Players don't need to install anything on their end, except for mod. You need to find .minecraft>config>ftbquests>quests. In quests should be folder and two files. So all you need to do is use existing ones or create folders config>ftbquests>quests, and copy the contents of the quests folder.

Medium-sized modpack crashing when loading new chunks occasionally. (crash report)

Maybe an issue with majruszlibrary or a mod requiring it

[1.20.1] Custom Effect Help

Currently stuck on making a custom effect for forge 1.20.1
Im trying to add a certain number of hearts to a player once they consume a potion/custom item, i tried doing it with the vanilla effects and it didn't work the way i wanted it to work, so now im trying to make a custom effect that adds this configurable amount of hearts

So far Ive been following KaupanJoes tutorial for both 1.21 and 1.20 and the effect doesn't seem to give any errors nor does its registration, however i cant seem to get it to work with applying it to the item itself

```package com.curseofaros.item; import com.curseofaros.effect.ModEffects; import net.minecraft.world.effect.MobEffectInstance; import net.minecraft.world.effect.MobEffects; import net.minecraft.world.food.FoodProperties; public class ModFoods { public static final FoodProperties FLASK_OF_LIFE = new FoodProperties.Builder()
.fast() .alwaysEat() .nutrition(0) .saturationMod(0)
.effect(() -> new MobEffectInstance(MobEffects.HEAL, 1, 2), 1.0f) .build();

public static final FoodProperties MEDIUM_POTION = new FoodProperties.Builder() .fast() .alwaysEat() .nutrition(0) .saturationMod(0) .effect(() -> new MobEffectInstance(ModEffects.MEDIUM_POTION_EFFECT.get())) .build();

public static final FoodProperties SMALL_POTION = new FoodProperties.Builder() .fast() .alwaysEat() .nutrition(0) .saturationMod(0) .effect(() -> new MobEffectInstance(MobEffects.HEAL, 1, 3), 1.0f) .build(); }

(Sorry for the real shi formatting, don't really know how to do it smh, note im also fairly new to Java so i don't know a lot, please be patient and let me know if the error is simply a lack of understand of Java principles)

Add the crash-report without the mod better_randomsource_concurrency_crash
