Good day sir!
First of all, you've created quite the lovely map.
We have a little problem with ours that I'm wondering if you've seen... Some time after the latest map update, we noticed these trains trying to spawn at big bases. They keep flashing on top of the bases, spawning in and then vanishing. We are running several plugins, of course, including the TrainEvent, so I unloaded that plugin first, but the problem persisted. I unloaded the TrainRustEdit plugin, and the train issue stopped, but then there weren't any work carts appearing anywhere. I thought maybe the work carts would still show, since I thought you had made that plugin optional now - I assumed the native train support might have still allowed them to spawn, but apparently not.
I'm making the wild assumption this is a map issue, so if I'm wrong, please accept my apologies. I just figure I'll check with you to see if you've noticed anything of the sort?
