I was trying to remove the old cargo wagons from my train distribution office and sell them at the border so I could buy better ones. The first load of wagons went fine, but the second one seemed to pick up "phantom wagons" that had no model and could simultaneously be used by the DO while my train was trying to sell them at the border. It got stuck at the customs house eternally trying to sell them, so I saved and reloaded my game to try and fix it. The train successfully sold the non-phantom wagons and returned to the train depot, where that monstrosity in the first line was revealed. The game has somehow decided to include a bunch of random vehicles across the map in that train, including multiple in use cargo wagons, two trams, a newly manufactured locomotive, and a fire truck. I moved the affected vehicles I could into the train depot and now they're listed twice. You can see five liquid wagons in the list but only four actually exist, for example.

Is this a known glitch? Is there a simple solution to fix this? I can sell the train to make this immediate issue go away, but I ran into a lot of crashes afterwards. I think the game was occasionally trying to reference one of the glitched vehicles whenever a crash happened. So if possible I'd like to handle this more cleanly in a way that won't make the game freak out.

Please help my unbork my glitchy vehicle situation
