So, I accidentally selected "Resume Journey" from the menu. Quit as I didn't want to do it, went to the route selection screen and... ...this happened. Thankfully it resolved itself, but never had this before.
I’ve had this randomly happen before to me sometimes something gets added with no name not sure what is it though.
I had that last year on PC after an update mangled my install and I had to do several Steam file validations to cure the problem.
Yes, this happens when I accidentally click on an old save (I never use the save game feature, so for the first few weeks of TSW5, I had a save from TSW4 that I would occasionally accidentally click on when trying to get 'to the trains'). It normally fixed itself after a quick restart of the game. Now, that button has been replaced with the option to continue the Sherman Hill journey. I don't click on that button, but I reckon that if I do, I'll get this issue again.
