@BoredEngineer I thought that message was always down to the engine version in the .uplugin file. Have you set it to “4.16.0”? Assuming it’s working in editor, it seems like it can’t/isn’t trying to load your plugin module in non-editor build. Do you have an entry for the plugin in the .uproject file, and an entry for the module (with type=Runtime) in the .uplugin?
@ponxalot It looks like it’s not rebuilding the module for some reason. I’d first try a full clean and rebuild. If that doesn’t help, you may be missing an entry for the module in your .uproject, or perhaps it needs adding to the ExtraModuleNames array in the .Target.cs file.
