I tried installing this mod with just AE2 and itself installed as part of some troubleshooting, only to discover that, despite what the Cursforge Dependencies page says, this mod isn't dependent just upon AE2, but also Cloth_Config, Architectury, and Curios. Please update Curseforge...

ae2wtlib has different dependencies for different versions.
They should all be tagged correctly.
The latest versions (1.21.1) require just ae2 and no additional mods, and it seems like this is the info curseforge displays in the non-version specific dependencies tab.
