So I downloaded Horizon, disabled Opis, and added Zan's Minimap (I prefer it, that's beside the point though), and it was working fine. I started experimenting by adding other mods but took it too far and it became unstable, so I deleted the folder, and downloaded it fresh again. Now for some reason, every time I disable Opis, it just generates a second Opis that is enabled.
So to clarify that last part, looking in the mod folder, I disable Opis and it changes the file from "Opis-1.6.4-1.0.6.alpha.zip" to "Opis-1.6.4-1.0.6.alpha.zip.disabled", then when I launch Horizon, it creates a second Opis. So then I have BOTH "Opis-1.6.4-1.0.6.alpha.zip" AND "Opis-1.6.4-1.0.6.alpha.zip.disabled"
Even if I just delete Opis from the mod folder entirely, it just recreates it. It won't stay gone.
I don't know why this worked the first time and won't work since.
One thing I'm gonna try is just renaming the Zan's Minimap file to "Opis-1.6.4-1.0.6.alpha.zip" to try to fool the client.
Edit: This didn't work either. It just overwrote the Opis file to be Opis despite it having the right name.
But seriously, what the fuck is going on?
