My problems are the trains and the overall zoom and I did not find any solution to my problem except downgrading my graphics to the absolute lowest settings.
The Train Problem
Every time i want to open the trainsettings to give them orders where to go, change colours or want to simply refill them, my whole computer crashes and i have to reload the game (luckily it loads very quit, GJ dev's

The Map Problem
Do you know the feelin? You just want to zoom out and watch your factory working. Me too but since i've started playing factorio i was never allowed to fully zoom out to see my factory. My game crashes (and the whole laptop with it) when i zoom out to much. Even going into the lowest graphic settings did not work. Has anyone a solution? And no, a new pc is no option at the moment
I hope i'm in the right forum-topic right now, hehe
