Minecraft Version

1.20.1

Mod Loader and Version

Fabric-0.15.3

Ad Astra! Version

1.15.8

Addon Mod Version (This Mod)

5.6

The details

1. I install Ad Astra, Ad Astra: Giselle Addon, and the necessary libraries. Then I start the game and the game crashes.
2. https://pastebin.com/gDwxbqVz
3. This may be due to an outdated version of the "Ad Astra: Giselle Addon" for Fabric.

same issues here, but an update would be better!

oh... I used the alpha version of Ad Astra which came out in January of this year...
