I have tried everything but I still TS19 is unstable. I have even downloaded the origin files several times from Auran, no luck. It seems to be something to do with Surveyor. I can run the default sessions from Kickstarter County 2 without issue until I try to close the game then it locks and the only way to close the game is to force quit. If I go into surveyor and try to add rolling stock the selection tab jams half way open and I cannot doing anything else except close by force quit. The game was working fine for the longest time. I did not notice if it was caused by the SP4 but the timeline seems about right. I made a screen video of what is going on but not sure what is the best way to share to this forum.
On a side note, I don't understand why my Trainz Member info shows TS 2 Mac and not my TANE and TS19. I have purchased all those versions. I am using the same log in for everything.
Thanks.
