I'm giving up. I've gone through this entire comment section so many times now. This just isn't worth it.
I've installed Udon. I've installed Orion3. I've installed Akar. I know these are installed correctly. I've made new plots, new regions. Orion works, the road menu just will not populate with anything.
Someone had the same issue and it didn't look like they had it resolved either. The author should definitely add that there are mods that need to be installed before installing this one. Considering that this mod was just featured on IGN, you're going to have more frustrated people downloading this and running into the same issues. You might want to update this.
I'll check back next year to see how much progress there is.
