Features
Modify the loading screen Heavily based on and inspired by Quilt Loading Screen
This feature is turned off by default and can be turned on through
config/bugjump.json
Fixed a crash caused by multiple rendering threads calling fastutil at the same time when too many client modules were
installed- for example
java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 513 at it.unimi.dsi.fastutil.ints.Int2ObjectOpenHashMap.rehash(Int2ObjectOpenHashMap.java:1334) at it.unimi.dsi.fastutil.ints.Int2ObjectOpenHashMap.insert(Int2ObjectOpenHashMap.java:279) at it.unimi.dsi.fastutil.ints.Int2ObjectOpenHashMap.computeIfAbsent(Int2ObjectOpenHashMap.java:500) at net.minecraft.class_377.method_2011(class_377.java:137) at net.minecraft.class_327.method_27516(class_327.java:57) at net.minecraft.class_5225.method_27496(class_5225.java:41) at net.minecraft.class_5223.method_27477(class_5223.java:17) at net.minecraft.class_5223.method_27473(class_5223.java:120) at net.minecraft.class_5223.method_27472(class_5223.java:84) at net.minecraft.class_5223.method_27479(class_5223.java:80) at net.minecraft.class_5225.method_27482(class_5225.java:40) at net.minecraft.class_327.method_1727(class_327.java:364) at net.minecraft.class_329.method_1754(class_329.java:651) at net.minecraft.class_329.method_1753(class_329.java:238) at net.minecraft.class_757.method_3192(class_757.java:862) at net.minecraft.class_310.method_1523(class_310.java:1177) at net.minecraft.class_310.method_1514(class_310.java:768) at net.minecraft.client.main.Main.method_44604(Main.java:244) at net.minecraft.client.main.Main.main(Main.java:51) at net.fabricmc.loader.impl.game.minecraft.MinecraftGameProvider.launch(MinecraftGameProvider.java:461) at net.fabricmc.loader.impl.launch.knot.Knot.launch(Knot.java:74) at net.fabricmc.loader.impl.launch.knot.KnotClient.main(KnotClient.java:23) at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:104) at java.base/java.lang.reflect.Method.invoke(Method.java:577) at oolloo.jlw.Wrapper.invokeMain(Wrapper.java:58) at oolloo.jlw.Wrapper.main(Wrapper.java:51)

Does BugJump need to be installed on the Minecraft server?
No. Modrinth marks BugJump as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.
Which version and loader does BugJump require?
Use a file for fabric and your exact Minecraft version. Supported versions include 1.20.1, 1.19.3, 1.19.2. Files for different loaders are not interchangeable.
BugJump is not working – what should I check?
First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
