I can get into minecraft, but when I try to load a world I get black screen and a crash. Sorry if this might be a little noobish.

Running on forge 14.23.5.2768
Mod List:
CubicChunks 1.12.2-0.0.1055.0-SNAPSHOT
CubicGen 1.12.2-0.0.115.0-SNAPSHOT

VanillaFix 1.0.10-150
WorldEdit 6.1.10-SNAPSHOT;8c1f930

ps. I have tried it without schematica, and still the same thing

Well first why do you have schematica and litematica which i dont even see in there? And also do you have malilib? Third a latest.log is always helpful

debug-4.log

Also, I just removed the mods since they were causing issues, and schematica is there so I can copy and paste builds easier

It seems that you dont have the correct versions of both mods
Make sure you malilib is up to date as well as litematica
Here is masa's site

debug-5.log

I downloaded it from your site, that's how it came. I tried the version that isn't deobf but still is the same issue.

Then post the crash log for the version from my site.

Found the issue, It was VanillaFix. There seems to be an initiation when the world loads and vanillaFix thinks that minecraft crashed.

malilib-forge-1.12.2-0.10.0-dev.23-deobf.jar
litematica-forge-1.12.2-0.0.0-dev.20200418.234108.jar

I assume you compiled these yourself? At least the malilib version is not the correct file, you are not supposed to use the -deobf version in the normal obfuscated game instance.

Also why did you compile malilib dev.23 yourself? There is already a build of that version on my server (linked above). Unless you merged the current master branch (LiteLoader) to the forge branch, there is also no point building Litematica again from the currently pushed forge branch, as that code is already in the December builds on my server.
