Screw rails

I've been playing this game on and off for 6 years. I think ea has made an absurd feature with rails. I have to have it for hom upgrades?? (I don't want to reset everytime. it's not efficient) 

So I was building a new rail at green valley cause I have space. But the game keeps in crashing when I made new rails connecting to the bridge from the first to the middle island. Please help me. Is there any fix I can do on my part or do I just wait for this game to patch whatever bug this is.
