The name of version 2.0.1 for 1.20.1 Forge is just named v2.0.1 - 1.20.1 - Forge.jar without Cave Dust in the file name. This makes it more annoying to troubleshoot for issues involving this mod on servers (as the mod attempts to load client resources on the server). I'm no mod dev, but I believe Forge has a tagging system for this to separate client and server code, it's a good practice to use that. Forgive me if I'm wrong

i don't actually have that file anymore, will be archiving that version as result, sorry for being a pain! this was a mistake from my younger self

actually i'll just try and rename it, CF is being a pain as usual
