Xbox Major Lag On Xbox 1s When Passing Trains With A Custom Livery (makes Game Unplayable)

I have lots of custom liveries downloaded for various trains. Whenever I go past them in Scenario Planner or service mode the game lags to the point where the game is unplayable. 99% of the time I don't even want the liveries to be there. For example I made a bullet train style livery on the 395 just as a fun project. The livery spawns on a 395 when I'm playing in service mode on SEHS. It completely breaks the immersion seeing this and it causes major lag. I was pulling into Ebbsfleet as well when I encountered another 395 in a GWR livery I downloaded. Again, I don't want to see a GWR 395 on the southeastern route. This time the game lagged so bad and the game crashed. This could be resolved if a percentage chance of spawn feature was added to custom liveries depending on route. If this was put onto place, the game wouldn't have crashed in the first place. I could just uninstall the custom liveries I downloaded but this defeats the point of Creators Club all together. Hopefully this can be resolved. Thanks.
