I know recently ARK updated their taming multiplier to 2x. Is that auto-updated here as well?

They recently updated a lot of multipliers in the base code. As clean as it is for them to say 2x, it's a bit more complex than that. What it amounts to is the algorithm now outputs a result that is twice of what it normally was when you have the setting set to 1.

But as this was the base game code they updated, it applies everywhere.
