Hello!
I've been working on a launcher based on the Helios Launcher that would let people play on my server with the mods being automatically installed. I'm not sure if this is an issue with Helios itself or something with the way Forge/Betweenlands reads configs, this modpack loads without issues on Tlauncher and the official launcher.

Versions

Betweenlands version:

3.7.3-SNAPSHOT

Forge version:

1.12.2-14.23.5.2855-universal

Java version:

OpenJDK-8 on Ubuntu 20.04

Description of the problem

How to reproduce:

1. Run launcher from: https://github.com/HUSKI3/Brassica-Launcher
2. Open the console of the electron app using ctrl+shift+i
3. Try to launch the game

Expected result:

Game should load the mod like normal.

Actual result:

The game does not launch and shows that it has an error while loading:

Caused by: java.lang.IllegalStateException: Something went wrong, Latest (null) did not point to an entry in the json list: /home/linkus/.brassica/common/modstore/angrypixel/TheBetweenlands/3.7.3-SNAPSHOT/maven-metadata.json

Pictures:

did you find it?

Nope, switched to another launcher boilerplate and this never happened again. I've tried to repeat this process with manual commands on my system, couldn't get the same error.
