Hey, I am new to the pack. Loaded up the Skyblock version of the pack for the first time and I got these messages, which persisted even if I made a new world or reinstalled the pack.

After speaking with some peeps on the Alchemistry Discord, it seems to just be due to the Earthworks mod not being downloaded by the launcher. I am using GDLauncher if that makes any difference also.

Thanks.

After doing some research it turns out that the Earthworks mod was archived on curseforge as it's no longer maintained. I'm already working on a fork of it to release it again. After that it will replace the Earthworks version currently used in the pack.

Earthworks should no longer be a proplem with the next version as we switch to a maintained version of earthworks.

This leaves ExtraCells2 on the table.

Great news. Someone forked ExtraCells2 to keep it alive. So the "missing" mods bug should be fixed with the next version. (at least for now)
