Hello, this is really strange, because this was tested quite a lot and it doesn't crash for me in 0.11.3, do you have a save with instructions how to reproduce it?
Yes I have a save. I must only run into nw and but the locomotive on my track and a few seconds later the game crash.
Where should i Upload my Savegame?
Sorry about my late answer but I was busy in real life the past few weeks. I played factorio yesterday after a long time, and the save game works; no crash.
The Game updated to a new version automatically. And with these version it works.
So I think the Problem is solved. But don't ask my why, I think the update solved the problem.
