For context, Rubia has an eyedrop tech that expands the player’s zoom extents. If Rubia detects the presence of any mod that explicitly alters zoom extents (hardcoded in that file), Rubia will instead cancel the eyedrop tech and associated script. This prevents the scenario where 2 mods are both fighting over making modifications to the player’s zoom extents.
As Rubia’s hard coded list (or even logic behind this) may change in future, I recommend not assuming that this prototype is guaranteed to exist. I try to avoid technology deletion, so Rubia does a check before the prototype is created.
