Viewing post in Aric's Expansion Rebred
I guess I should clarify, you have the same issue now as you dd then and the same solution. The first line of your screenshot says "Godot Engine v3.1.2..., which only appears in version 1.0a of Strive and Aric's mod still only works for version 0.5.25 of Strive. The sub-thread beginning with the linked post explains this same issue and provides a link to the solution (https://itch.io/t/975848/strive-v525-arics-expansion-v097-pre-merged).
