Thanks for letting me know about that dependency. Of course it shouldn't be like that. Somehow when i made the dependencies for that loco the workshop decided to link them backwards too, i have missed this one when fixing it.

Now, this mod basically does exactly the same thing as the normal Rail Mod bogies, it just makes them have another model and float on different heights. Blueprints also do not add their dependencies automatically, you just cannot paste them if you're missing mods.

That being said, with how unstable any mechanical things are in multiplayer currently, it is a bad idea in general to use trains in MP as it is pretty normal for them to fall apart and desyncronise constantly.

If the problem is still occuring now that i removed the dependency, please feel welcome to join the linked discord so it'll be easier to try to solve the issue.

Somehow I think your mod is making my server go haywire and it added the mods required for the locomotive blueprint (why is there even a blueprint dependency in a mod?) and now i can't get rid of this mod or the locomotive blueprint somehow, even if they are deleted from the mod list they still show up, and clients can't connect, I have spent a total of like 6 hours troubleshooting and this is the most logical i can come up with. Why I think it is this mod and/or the blueprint because those have dependencies for all mods that the server added by itself after a restart, and your latest update also falls perfectly into the timeline.
