im trying to upload my mod to the workshop but whenever i press publish my game crashes, my map is quite large and exceeds the white square, it might also be that the map has no scripting at all and the construction of the map is a messy disaster since it is my first mod. I have uploaded a preview image as well so that cant be the reason, and ive made it public but it still wont work, pls help ive been working on this mod for over a week now.

Not sure why, are you on our Discord server? In that case ping me (@ONSVRG) and send me the mod and I can take a look.

sadly i am not on the server is there any way i could friend you via discord?

Just dropping the solution to this case here as well, the issue was a corrupted preview.jpg file.

can concur it worked after i replaced the photo
