The mod I have installed on my server is RK’s Highly Customizable Engines mod and the server says it has loaded 1 mod but when I join on my gaming pc there are no engines from the mod to be found. I am joining from a separate machine (Laptop hosts the server while I join the game on my PC both connected on the same network.) The server or game client throw no error codes also.
Make sure the mod is still zipped
The mod also goes into the Resources > Client folder
The mod is zipped, and in the client folder.
