I'm basing this issue on testimony from the Curseforge page:

That said, this mod is designed to be able to run without Applied Energistics 2, but installation with it is recommended.

TilePackagerExtension implements AE2 api interfaces without @optional and is classloaded even if AE2 is not present.

Just tested this and both of my issues were resolved by the new version.
