TileEntity

And without BOP and Terralith?

You can try Rubidium + Oculus as alternative

Change the Java 8 build https://www.azul.com/downloads/?version=java-8-lts&os=windows&architecture=x86-64-bit&package=jre&show-old-builds=true Scroll down to 8u302b08 and install this build Then edit your start.bat and use: "C:\Program Files\Zulu\zulu-8-jre\bin\javaw.exe" -Xms1024M -Xmx6144M -jar forge-1.16.5-36.2.20.jar pause

Make a test without Optifine

Maybe one of the "Better" structures mod is causing issues with BOP/Terralith Remove the stucturemods like BetterFortresses, BetterJungleTemples etc one by one

I have no idea - still an issue with valkyrienskies Maybe just use the Zink Flavor 1.20.1 modpack as working base and add/remove mods

It is an issue with MaFgLib Maybe these issues refer to Optifine - make a test without Optifine

Try other builds of these

Remove all mods and make a test just with forge - if this works, add the mods one by one or in groups

Make a test without XaeroWorldMap

Delete the config of valkyrienskies and test it again

yes

Make a test without wythers

Create a new modpack instance and start with valkyrienskies and embeddium Use the mods from the modpack If this works, add the rest of your mods one by one or in groups

There is an issue with immersiverailroading - maybe a conflict with entity_texture_features

It is a fork of Rubidium - test it with embeddium

Maybe an issue with architectury or a mod requiring it

Copy/paste the mod builds from this modpack to your own and test it again

Use Java 17 instead of Java 18

Make a test with this build: https://www.curseforge.com/minecraft/mc-mods/epic-fight-mod/files/4029362

Add crash-reports with sites like https://paste.ee/ Make a test without epicfight

Add the new crash-report

This modpack is using Connector which is able to load fabric mods via Forge The mod fabric-renderer-indigo is causing issues - start with removing this mod

Same issue without fancymenu?

Try an older build of Rubidium
