In a thread I opened on this update there has been a report of the 387 and walking around causing UE crashes. After I got this update, did a file verify with everything coming back OK. I opened LBM and went into a walk and crashed as soon as I moved the mouse. Then went back in and ran a 377 service out of London and crashed to desktop as I was approaching Chappham Junction. Don't know what others are finding but for me its unplayable. I should note that the patch for this passenger issue was already loaded into the system the end of last week and I played service 1M5 yesterday without problems. So what was in today's download which then made the entire LBM unplayable.
Try verify the game integrity if you are playing on Steam. Had the same problem a while with an update for DRA and a verification solved the problem.
Well, I found out something today. I verified the download this morning soon after it finished installing and got no issues found. Then, LBM would not run crashing to the desktop with UE issues. I was going to uninstall and reinstall TSW, but decided to do the verify again and this time it found something which when corrected allowed me to run this route. The fact learned, DO NOT do that verify until after your start the route and it crashes. Interesting fact was, most of today's update was for SH and that route ran fine after the install.
