Yesterday when I loading the Quick Drive of NJ North Jersey Coast line from Point Pleasant Beach to Bay Head, the screen turns black and jump out to the Window, and it displays that was out of memory. But when I launch that again and reload the same scenario, it works. What happened?
TS20xx Happened, welcome to train simulator. Seriously, search "OOM crashes" and "dumps" on this and other train sim forums you'll soon see what I mean.
I wouldn't get too worried about it. I have had these but not since TS2021 was released. I just restarted TS and continued driving and forgot about the OOM. It would be a different story if you continually got them by doing the same thing all of the time.
